So just from comparing my MX-500 to the MX-700...knowing that the MX-500 can be had now for about $80, and the MX-700 for about $180...is it worth it?

If you do not mind spending the time to customize the 500, then the answer is probably no. If you do not have more components than the 500 can handle.....programming it takes time, but if you are patient, you can probably get it to give your the same convenience that the 700 offers.

Now if you want the ease of programming, and thought about getting the IR-Clone package to customize the 500...which is also about $80, then it is a no-brainer. The MX-700 and editing software has by far and away better capabilities and is worth the extra $20. What I just did with the 700 in 30 minutes would easily take me at least an afternoon with the 500.
