Query: Buying Nightmare

I am so sick of trying to buy a GPS system. I just wanted a GPS like the one in a rental car I had recently, instead I have to compare 30 different systems (and that's just Garmin's "on the road" Automotive category) across 50 different "features" not including price. I'm exhausted with the whole process so I settle on this model and now I find out it doesn't have "street name" voices. I'm always going to remember this experience as distinctly unenjoyable.
