Just to add a few additional remarks to Art's post:
The Epson V750 has sufficient scanning quality for most general applications. It is NOT at the same level as a halfdecent drum scanner just yet (well, what did ya expect from a little 800$ scanner).
If you want to use it for scanning 35mm in good quality, look somewhere else too (almost ANY dedicated filmscanner can do better here). For 120 and up, it's a different story. With these larger film sizes (up to 8x10) the Epson delivers an unbeatable quality vs. cost ratio.
Oh, please forget about that "wetmounting" gizmo. It's a toy for Sadomasochists only - you spend condsiderable time with highly volatile chemicals trying to get your film wedged between glass and mylar in a futile attempt to avoid air bubbles, all for a minute speculative improvement in the scan. And it won't do 8x10's - the holder is too small.
Nevertheless, if you know where the scanners limitations lie, it's a good bang for the money; just don't expect any miracles. And yes, I have the V750.
PS: For people who don't need the colourmanagement software and wetmount gizmo, the V700 is virtually idential (almost) and costs only a fraction.
