Here's one of the new waterproof cameras we're trying out: Sony DSC-TX5. Nice camera that takes good pictures and video. Reasonably easy to use with long-fingered gloves on today's cold weather ride. And it's waterproof, so if we get stuck in another rainstorm (or if we go for an underwater ride) we'll have one less thing to worry about.
We bought this particular camera used on eBay for about $55. Saved about $150 by accepting a few scuffs ... and the pink color.
We'll post some sample photos soon.
