KCDW - why the down on aviation databases? If you are using it as a VFR backup there is no need to update every month. Every six months would be fine and you have the security of all those waypoints always available inflight.
I use a GPS92 - it's small, light, uses batteries sparingly, can be used with yoke mount, portable antenna, aircraft power supply, PC link as required (or not if you are a true dino). The moving map is more of a diagram - but it is still pretty useful. There is one on Ebay this week at £120 (people moving up to pretty colour map models).......
