I'm dreaming to own an Epson Stylus Pro 4000, but its price is not feasible for a hobbyist unless I start offering A2-size printing service.
A4 and A2 are the closest to 3:2 aspect ratio, similar to 35mm format while A3 is somewhat 4:3 ratio, similar to some digicams. However, since i only shoot with my SLR and DSLR most of the time, I would very much want to print in either A4 or A2 size. Got tired of seeing my photos in A4 already, that's why now dreaming of A2 printouts.
Currently printing my own photos using Canon's MPC200 which uses combined colour cartridge BCI-24C. Smudges easily. The next printer I'll buy would be an Epson using either DuraBrite or UltraChrome inks (for its waterproof capability).
Given the choices above, I'll go for Epson 2100 now, until Canon solve their famous fading problem and comes up with waterproof ink.
