Try going to the
Clicker Picker on this site. There are a number of items you check off as to what you need in a remote control, and then it suggests which ones you might like to look at. Most of them are also reviewed on this site.
It might help you in your search for your remote.
Once you've narrowed it down a bit, you also might want to check out the
User Reviews for people's experiences with the remotes.
Again, once you've narrowed it down, please ask any extra questions in the appropriate forum i.e. Universal Remote Control, Pronto, OneForAll, Sony, etc.
