A disposable camera works pretty good.
I took these with a one time use camera. To put them on the web, I just scanned them. I have some nice pictures for my photo album and pics for the web. Cheapest way I know. I also have a cam corder that can take pictures. I've seen a $39 pen camera take some awsome pictures too. It's all really in the lighting. My preference is probably the Sony line of cameras.
