While we wait patiently for camera manufacturers to realize that geotagging is a much more compelling feature than yet another megapixel, we'll be building this DIY GPS attachment for the Nikon D200 instead. Just like the $400 GeoPic II, the box is based on a SiRF Star III chip, but since you're building it yourself, you'll wind up shelling out less than $100. While you'll need a steady hand and a bit of soldering skill, it doesn't look too hard to put together -- so what are you waiting for? Instructions at the read link.
