I forgot to mention my cameras, several of them. Rather than distract this thread, I'll save the details of that collection for a future thread.
I'm considering purchasing a GPS unit for two purposes: for geotagging photos, and for not getting lost while hiking. I've been looking at what's on Amazon, etc. to try to figure out which are crap and which are good. Whatever kind I get, I want to be able to save a record of the route and download it to the computer, preferably with an SD card instead of internal memory.
