For the Garmin stuff, GPSNow has the best prices.

I just received my GPS V. Very nice - way beyond my old GPS II+. I especially like the "recalculating route" feature when you miss a turn (or duck to avoid an accident).

GPSNow shipped two day fed ex, and I received it the next day - very nice service, though I'm not sure if that counts towards GPSNow or FedEx...
