One thing to consider is that you have roughly 8000 cubic feet so if you are at all into "wanting to rock the house" don't go smaller just to save a few bucks. Maybe wait a bit till your budget has more $$$. In the long run you'll probably be happier. I have an EP350 in my bedroom and it does fine there but it would not cut it in my great room....roughly 14000 cubic feet. ( Though the EP600 shakes my world.) The 60's will do a fine job for you.
Another thing that I haven't seen mentioned in your budget.....don't forget that after all the hardware you're still going to need at least a couple hundred $$$ or so in cables and interconnects.
No matter what you get enjoy it!
