The DTXpress IV sells at Guitar Center for $999 brand new. Sure, you don't get the bass drum pedal, throne, or sticks, but at least it is new.

If you like the Yamaha stuff, you could look at the DTXplorer.It is $300 less than the DTXpress IV. It has 18 fewer drum kits and a few other differences, but again, you are just getting started. Mario Andretti's first time behind the wheel wasn't in an Indy car. His first "car" was a lid to one of his mom's pots and he went around the house going "vrooom..... vrooom..."

Besides, the Yamaha stuff isn't "Indy" level anyway, but not bad for a newbie. :-P

Considered by most to be the best "electronic" drums would be the Roland line-up. Take another look at the TD-3SW for $995.99 at Guitar Center. The biggest benefit just by looking at it is the mesh snare drum vs. the rubber one on the Yamaha. Beating on rubber pads will make your wrists sore after a while, and since you will be hitting the snare drum the most, this is a really nice step up. When I was looking for drums a couple of years ago (after being drum-less for about 10 years), I said that I would never go back to electronic drums. As a youngster, I had a cheap (really cheap) Pearl set that was beat to heck. My first new set was a Tama Techstar. They were great for a while, but boy did they sound like 80's synth and 80'd synth only. I regretted that purchase for a long time, and eventually just gave them away.

Then I was back in the market and was looking at Gretsch, Pearl, and a few others. I was about to pull the trigger on the Gretsch when I stumbled into my local Guitar Center and just starting looking around for some cymbals that I liked. I was waiting for the sales guy to finish up with someone else, so I sat down at a Roland TD-20S. I was in love, but couldn't pay the $6,000 price tag. So then I started asking all sorts of questions about the entry level Rolands, the Yamahas, and the Pintechs that they had out to play.

After messing around for about 2 hours, I went home and started looking online to see what others thought of the brands and models. After several days of reading and research, it was clear that I needed to stick with Roland, but I had also heard that the rubber pads would drive me nuts after a while. At the time, Roland only had mesh on the snare of a TD-6 series (over my budget), or all mesh on the TD-20 (way too expensive), so I was asking about getting a TD-3 series, but upgrading the snare to mesh (it wasn't a standard feature back then). I found out that Guitar Center would give me full price credit back for the rubber snare and put it towards the mesh snare. So then I started asking about upgrading all of the toms to mesh as well, and before you know it, I had upgraded the sound module from a TD-3 to a TD-6 as well. I managed to get a TD-6SX equivilent (which wasn't out yet) for $1500 compared to the price of the TD-6SX which came out 2 weeks later for $2100. It was over my budget, but I knew it was what I wanted. Roland also had a "rebate" for a free $100 pair of over-the-ear headphones, and a free 3rd cymbal or a PD-8 rubber drum pad. I went with the headphones and the 3rd cymbal, which is great. The bell of that cymbal currently is a wood block, and the edge is a splash, but I can set it to whatever I want.

Now the TD-6SX has a new sound module and is the TD-9SX which sells for $2500. I am super happy with the set and I am very glad that I went with mesh pads, but again, you are just starting out, and you may find that the rubber pads are just fine until a few years from now when, if you stick with it, find that you are ready for the next level. Then you can just upgrade the toms, or get an even better mesh snare, or whatever.

What you need to factor in, since I am not trying to get you to burst your budget like I did, is start with the "fixed" numbers. Start with the total to spend, subtract a throne, subtract a bass drum pedal, subtract a set of sticks, subtract either headphones or an amp (do NOT hook them up to your Axioms!!!) and see what you have left, then start looking online for deals and while you are doing that, check out a music store in your area that has a few to sit down and try. Just go there, put on some headphones and plunk away. Nobody cares if you are good or not. Pay attention not only to the "fun" sounds of electronic drums, but ones that seem to sound realistic. Look for sound control options on the drum modules so that you can tweak the existing samples to your liking. Look at the responsiveness of the drums themselves. Can you play them really, really softly? How much rebound do you get from holding the drum stick between your thumb and index finger and letting the stick's tip pivot and freely bounce on the drum heads. Too little and you will struggle to get any speed built up, too much, and it is like playing with those rubber "super balls" and you will be fighting to keep things under control.

Alright, well that is WAY more than you asked for, but I hope somewhere in all of that is some useful information.
