Ah the ricoh. I've sold a lot of ricoh film cameras back in the day. My understanding was they got out of the camera buiness to focus on copiers. I guess digital pulled them back into the market. In my experience they were hit or miss. A lot of models were crap, but they did have some real gems at great prices. Still IMHO you are better off getting a digital camera that you really like, and a housing for it if you are seriuos about wanting to take pictures on the water without having to dry off first. That said I would definately not mail order the ricoh. Buy it somewhere you can return it easily if you are not satisfied with the quality. You not only have to look at optical quality but chip quality as well. Not all 3 mega pixels are the same. Also it looks to me that the ricoh Capilo 400g is this camera http://www.seaandsea.com/DX3000.html
with the housing made permanent. www.digideep.com
has a list of cameras and housings available for them. Sorry too go on and on. I'm not much of a paddler so I rarely get to contribute.
