Being a cheapskate I got a second hand Epson GT700 photo scanner for £50 (off ebay). The transparency adaptor is ideal for scanning my MF negatives for viewing on screen. I have tried printing results (12X8) via an online printing service - but it is in the post at the moment (a particularly difficult negative which I am also still trying to print in the darkroom - this was a last resort!).
I find it useful to be able to see large contact images of negs before hitting the darkroom (the reason I got the scanner).
