Thanks. After reading thru recent posts on the subject and researching on my own, the latest Garmen 60 and 76 series seem to be most suitable for the things I would like to do. I'd prefer regular SD cards instead of the micro cards, as I already use SD/MMC in my Palm Pilot and digital camera - or CF, as I have plenty of those sitting around, but... The Magellan Explorist would be a little cheaper, but I'm a little put off by the position averaging and a lot put off by the battery pack - sticking to standard AA makes more sense to me.

Does anyone know the differences between the 60Cx and 76Cx? I'm guessing the 60 has a helix antenna and the 76 has a patch antenna, but other than that, it looks like a $50 difference gets a 128mb card with it instead of a 64mb card, so it must be mainly the internal antenna difference - or am I missing something?

Also, it looks to me as if I can upload Delorme Topo USA maps (custom maps?) to these. I'm assuming it won't be the vector based versions, but that's OK on the unit - I'll continue using paper and compass for navigation. So - will these use the Topo USA files?
