Bump, I've been looking at a GPS for pizza delivery (hey the economy sucks) and decided on a 2136TLM
by Magellan. So far it's served me quite well, from delivering local back roads to taking trips from state to state visiting family.
I'd recommend it, if you guys/gals haven't found something yet. The screen is big enough to see but isn't large enough to get in the way. Contrast is pretty high and battery life is quite good, just make sure to let it die a few times a week to keep it from getting a memory!
