What band(s) do you plan to be using?  I bought a dirt-cheap no-name 
inverter at Target and it worked fine in a UHF contest at 222, 432, and 
1296. The next time I took it out in a VHF contest, I found that every 
time I transmitted on 144 it would stop working.

I now have an Astron inverter, and it seems OK for 144 MHz and up, but I 
think it does raise the noise floor a bit on 6M. It might be a problem 
on HF (but I haven't tried that). I used it at Field Day to make sure I 
wouldn't lose AC power to the rotator if (when) the generator ran out of 
gas or someone tripped over a power cord. (The radios were DC powered 
and I had a pair of gel cell batteries in parallel with the output of 
the DC power supply, so that part just kept working, sort of like a 
do-it-yourself UPS.)

Good luck
