D70 Prints

Hello,
I recently purchased a D70. I have considered purchasing a wide format EPSON inkjet printer. My question is: How large a print can I obtain without noticeable reduction in image quality? I have heard 20" by 30"; does this sound accurate? Is there computer software for Mac that can enhance the image for larger prints done on 44" wide sheets?
Any advise, thoughts knowledge appreciated.

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...
