I've come down to these two models and I can't decide which one to get. I guess my main quetion is, which is easier to program/setup. If you have either model, what are your likes/dislikes. Thanks.

What do you wqnt in the 700 that the much cheaper 500 doesn't have?

I've set up a 500 and it's pretty easy--lots of room for specific device buttons so you can make all the macros you need. Can't compare to the Harmony, but check remotecentral.com for detailed reviews.

Thanks. I read the reviews for the MX-500 and it's convinced me to pick it up, that and the fact it's $100 cheaper than the MX-700. Plus if I like it, with the money I've saved, I can pick-up another for the bedroom.
