A handfull
I had a 1st. gen. pronto. Great "cool" factor, but sucked on function. I hated having to look at the remote to press a button. MX-700 Great, loved it, had some issues with it being able to send long ir codes for chan. (eg. 1,2ms pause,0,2ms paues,0, just for Ch. 100. I had to keep adjusting the time between the numbers for every Ch. I did. Harmony second gen. Liked it, Like the online programing, but it would get "confused" some times. I'm using the sony RM-VL1000, it works, but programming is a pain, and if you make a mistake having it learn a code, you have to start all over, you can't reprogram just one button. I'll save up and try out the new harmony H659.
