Eric,

I've been using a Garmin Gecko for the last 3 years. Excellant basic GPS, but it doesn't have maps loaded on it. Got it since it was the lightest at the time. Now am using a Delorme Earthmate PN-20 loaded with Topo USA. I've been using Topo for the past 2 years with good success. It's been as accurate as USGS Topos. The PN20 easily interfaces with my computers. Also has routing for streets to address level, and points of interest ie gas stations, restraunts... So far with the hiking & kayaking its proven its mettle.

Before buying the PN-20 I considered the mapping Garmins (map software esp the nauticle charts too expensive) and Magellan. The Magellan looked promising since you got their topo software & coast marine charts for $200. However I've been using Delorme's Street & Address software for the last 10 yrs., so with the availability of nautical charts now (Delorme didn't used to have this) I went with the PN-20.
