>>488904You're not asking for much. What's your budget? Do you have $500 to throw at a kickass way-over-featured receiver? Or are you looking for something in the $50-80 range?
My recommendation, based on the limited information you've provided, is an eTrex Legend or Vista. Wouldn't go less than the Cx - Color screen and eXpandable with µSD memory cards. You'll want both of those.
The old-old ones (GPS12, III, V) will do what you want, but offer very little for additional maps and logging capacity. I could easily fill my GPS12's 1024-point track log in 2-3 hours of riding, and serial transfer to the computer took a while if everything was full.
Color gets you your choice of maps, and makes the maps easier to read. Memory card allows you to put a fairly large area on the receiver (There's limits, both file size and "tiles", but that's outside the scope of this post).
I ride with a 76Cx. I've had a 76CSx, 60CSx, GPS12, and Trimble SLGR. The 76Cx does everything I need it to in a nice package and without an overcomplicated UI like Garmin's newer models have.
Other mfgr's have similar models, but the software and mapping on them isn't nearly up to what Garmin has.
