The MX-810 would be good for a former Harmony user.
You could do this easily with an MX-850 or MX-900 (though the MX-850 lacks some DVR buttons). That would involve a total different style of programming...it doesn't guide you through anything, you have to manually do everything yourself.
You can easily punch through, macro, and shortcut buttons on those remotes to do what you want.
There are two members here,

www.proremotes.com, who are excellent authorized dealers. I reccomend them both.
