As far 35mm dedicated scanners go, I know of two places with a very good price option on a Nikon CoolScan 4000 and well the price is similar to a new 7600Ai.
Which should I go ? I shoot mainly Velvia/Provia and Rollei Retro / Tmax ..
I have a coolscan 4000 and just bought a plustek 7500i. the plustek in my opinion does a better job. However, through out the silverfast software and use vuescan if you want to stay sane.
