The wife and I both have a Delorme PN-40. She started with a Garmin and I started with a PN-20. We both love all the features of the PN-40 and the great tech support.
I have a Garmin Vista HC that I purchased a couple of months a go for the wife. It is in excellent condition. She wants my PN 20 so I'll part with with the Garmin for $130 shipped.
