Tired of my crappy remote. Any suggestions?

I'm really disgusted with the cheapo remote that came with my $5000 Sugden amp. Phillips RC5 Audio Control.
Have to bang it on the coffee table just right to get it to function.
I've changed the batteries, cleaned the terminals etc.
Can ruin an enjoyable listening session when you can't adjust volume etc. A real pain.
Is there a simple solution?
I'm really not looking for some complicated thing with alot of buttons.
What I'd like is somthing that has a feel like my Nokia cell phone with as few buttons as possible, a Volume, Play, Track selector is all I ever use.

Maybe best to move the equipment next to my chair and forget the remote.
