(A followup can be found here)

My habit of returning to camp well after dark has made me rather appreciative of handheld GPS units.  I had a GPSMAP 60csx that lived a good life before getting lost followed by a Oregon 450 originally intended to be a temporary solution that turned into something more permanent.

After my Garmin Oregon 450 GPS developed a habit of loosing satellites while under clear skies I ended up taking a look around at options while working my way through tech support.

I spoke to some rather helpful folks at the Garmin tech support number and they offered to ship me out a refurbished unit for $99.  Even better they would send me a unit out immediately and just charge me 2x $99 until they received my unit.  Not too bad!

Just to cover all of my bases I checked what the other Garmin models offered and saw there had been an updated Oregon released, the 6xx line.

Brighter screen?  More resistant to scratches?  Faster maps?  Better interface?  Rechargeable batteries?

It was enough to get me to drive out to an REI in the few precious hours before the next trip and throw down $500.
