I recently noticed that Surf Remote sells the MX-700 for $160 - a pretty nice price for that remote.
I'm going to set up an MX-500 for my in-laws this weekend (two-part Christmas gift: remote and setup/training). It's still a great remote, but I don't know if I could part with my
MX-700 in the main system anymore. I've done some fun stuff with it.
