I have a new in the box 60CSx. It came with window mount, dash mount, external window ant., pelican case, and California map chip. At first I was going to sell it, but I see prices all over the board from 199 (never can seem to reach this site) to 350 and everywhere in between. I would keep it, but I already have this same unit. While trying to find a realistic price, I started to read about how good some folks think this unit is. Now I am thinking I should just keep it as a back up to the one I currently use. Money is not really an issue, so what do you guys think? Should I keep it or sell it?
