This is a very helpful thread! I have been trying to decide if I should attempt to program the remote that came with my Rotel RSP-1066 (which IS a learning remote, but which is not the easiest thing to setup or use), or if I should pickup another universal learning remote. I, too, have checked out remotecentral.com, and it is a very good resource. My current faves are either the Harmony ST-659 or ST-768, the Home Theatre Master MX-700, or RTI Theatre Touch T2.
Man, those things can get expensive...
