I started with an RDF, moved up to Loran and have since been through 3 Garmin units. My newest is the Map76S. It's a bit chunky... and maybe a little overkill but is loaded with useful features.
The main use I have is bailing me out when I get lost on mountain roads (or the two-tracks around the Black River in Michigan!)
Just take the lat-longs off the GPS and transpose them to a newer Delorme map book and you're home free.
Even the most basic of units should give you lat-longs.
