I was stupid and didn't research as well as I should have before buying a new GPS. I realized today that the Garmin GPS 60 has all the features of the eTrex Legend except the built-in basemap, but it also has a few extras. The GPS 60 has a USB PC interface rather than serial, it has an external antenna, and there's no stupid rubber gasket or click-stick that'll fail in two years.

I'll be returning the Legend that I ordered to Amazon whenever it arrives (should be next week), and I'm just waiting for the price of the GPS 60 to get lower on Amazon before ordering (it seems to fluctuate daily). Right now the GPS 60 is $25 more than I paid for the Legend, but the Legend went up in price $10, then came down $15 in the two days before I ordered it.
