Billy, I still do a bit of photog with film.
I have a V700 which is price comparative to the one you are on about.
The advice I received from hobbyists and pro's incl a color mgmt consultant which I met at the camera club is that high end consumer flatbeds are ok for medium format film but for 35mm they may not provide enough real resolution given the smaller 35mm size.
Given the price of those units $600+ arn't they, you may want to get a $400-600 dedicated scanner on Trademe, they are pretty much discontinued unless you get the medium format version new which is insanely expensive in NZ.
People have said a flatbed scanner may have a real resolution of 1,000 dpi, if you scan anything higher it's just larger filesize.
Re: time. It varies considerably. If you scan 4000 dpi which is what dedicated scanners do, flatbeds may spend 5-8min per shot, yes with ice, I think if you don't use ice a shot may take 1min If you doing strips automatically that would just increase proportionally. I've never scanned strips in high reso, only small reso, too painful on the hard drive space and too long.
Re: auto scanning strips. If the shot is quite dark and stuff, it could crop your images. LIke the top and bottom is cut off (esp fireworks or dark indoor museums etc) You may also get shots in between the two - like half of frame 2 and half of frame 1. You may need to resort to manual scanning per shot and maybe increase the brightness just so that you can see the film mask, make your crop selection and then preview scan again and then fully scan it etc.
I got the flatbed b/c I intend to get into sheet film. If I was just doing 35mm I would of gotten a dedicated scanner for the same price (new at the time) and way better quality. The thing between flatbeds and dedicated is the dmax, dedicated scanners are able to extract more shadow detail. A more $$ flatbeds will do a similar job compared to say a cheaper flatbed. If you just want a record scan any of the cheaper flatbeds will do.
