Mike,
Harmony makes the 659 remote that has a regular LCD (non-color), but uses 4 AAA batteries for power.

I've installed 6-8 of these cor customers and they work well.
The 880 is rechargable because it's much more power hungry with the color screen. Even is you could use regular batteries in them, you probably be replacing them each week.
If you have a DVR device, Harmony makes the 670 which is similar to the model I linked above, but more geared towards systems with digital recorders.
Cheers,
Paul
