on ebay you can find a body for about $100. and since it has a EF lens mount you can find lenses fairly easily. also, since the pictures wont take up so much memory due to the camera being 3.3mp, a 1gb CF card would be plenty.
i plan to spend about $200 for the body, lens(es), Cf card, batteries, and maybe the flash.
ive also found a very in-depth review of the canon D30 here.
