Digital BW, The Print

I'm at the point where I would like to get a 24" Epson printer and was thinking of buying a 
used 7500 or similar. I'd like some input on this specially regarding compatibility with 
QTR+UT2, pricing, etc. Considering the price may be close to Epson 4000 what would be 
the pros and cons to buying that one.

Thanks, Andu
