Todd,

I'd second Allan's comments.  The battery capacity meters from ETA are 
probably the best deal you're going to find if you're trying to shave some 
bucks off the cost of a Tri-met or E-Meter.  I have a lot of experience 
with the "low-cost" general purpose digital panel meters, and most of them 
have +5V or +9V power inputs -  they're intended to be designed into an 
instrument, not for use as a system-level component.  By the time you get 
to process meters with 12-48 VDC power and signal inputs, self-contained in 
a protective case, you're up in the price range of the standard RE 
monitoring instruments which do quite a bit more.  At least that's what 
I've found in my travels.
