I just bought a Legend HCx and love it. easy to use, compact. It has the color screen, memory expansion for added maps. I ordered it off amazon for $199ish...
We just started recently but I find it easier to just delete the found ones once we get home leaving only unfound ones in the GPS. I like to keep it loaded up with a bunch to find just in case we have time to stop and take a look for 1 or 2 (not that we've had a huge amount of time lately).
