G10/11 appropriate for 3D artwork or which camera?

I'm familiar with the early powershot series (have a G3) which has appeal given my limited camera experience. I've read good reviews for the nikon d40 though the minimum ISO is 200. The G11 looks good but is not out yet for much review.

I need to get strong photos of my fine artwork ceramic sculptures--see my site for examples. I'm planning on using a softbox (have to figure out that too) and other set-up tricks to add dimension, etc., but I need a camera designed primarily for this purpose. My surfaces tend to be subtle with colors softer and warmer. The rebel slr was recommended but I think is beyond my abilities and pricey (I'm writing a grant proposal for this and crossing my fingers).

James, you gave me the confidence to put down that the right camera for my needs was either the Rebel T1i or Nikon D5000 in my grant proposal. Now should I not get the grant.....I may have to stick to my G3 a while longer and keep a lookout for those others you mentioned. Thanks for your reply!
