I just picked up a Fuji FinePix 2650 2 megapixel camera and it seams to be working out ok. It has a short 4 inch macro focus depth and the ability to lock focus so you can set a focal point for cleaner shots. The best thing was the price $199. Most other cameras in this price range don't have the macro option. The camera also accepts some macro lens addons. If you are takimng pictures mainly for the web I would recommend it. They also have a 3 megapixel version and I think it goes for $300. It also has their Ultrazoom so the macro focus is good from 1 to 18 inches.
As for scanners, you may want to look at Microtech or Agfa. Micortech scanners can be had the cheapest and have a decent depth of field. In the case of Agfa you pick up a little better color accuracy.
