I've heard of people getting sweet 20x30 prints from their D70's...Of course, it really depends on how close to the print you'll get...As far as enlarging goes, I think most people do the 10% increment method, enlarging the image in 10% steps. I think that PSCS can do enlarging well without the 10% method though...also, I think that programs like Genuine Fractals are pretty effective for making large prints, but I've never used one of them...
