Garmin nüvi 750

Pros: Cheap, usually reliable, good battery life

Cons: Slow, sometimes offers odd routes

Summary: Good deal for the $$, but you get what you pay for. The reception has been great in Phoenix/Metro up to Vegas and Cali. I have not once, even while in a mountain pass, lost reception. Battery lasts several days with moderate use. It's usually very accurate however sometimes it gives you strange, non efficient routes, and usually by the time it recalculates your direction you've missed your turn. I would advise this unit for light travel and to navigate a city that you are somewhat familiar with.
