Epson V700 is a good choice for MF.
Just optimise the height of the film holder (I quit on the Epson and bought a BetterScan holder) and the curvature of the negative (with the BetterScan holder I bought a Anti-Newton glass). In my case, the difference is big.
Don't be afraid to use unsharp mask: the V700 is a bit soft, so it needs it and grain won't be very visible after the mask.
I also have a Minolta Multi Pro and with proper technique (good, adjusted holder, flat film and unsharp mask on the V700) they are almost equivalent until 1800-200 dpi. Of course the Multi Pro goes to (real) 3200 dpi and the Epson maxes out at around 1800-2000 (although it's rated at 3200 dpi).
I posted a thread comparing both some (long) time ago.
Before the V700 I had a Perfection 3200. My first MF scans on the V700 were a let down (much worse than the 3200). After adjusting height, the V700 is clearly better. It's just that the depth of field on the V700 looks to be really small and the holders are not factory optimised for each scanner (my particular sample could only be adjusted with the spacers on the largest height and some more shimming...).
Even for 35mm on the web (or small prints), the V700 is ok.
You will read a lot of very different opinions on the V700, and part of the problem is precisely this one: some people get lucky and some unlucky people don't bother to optimize. I almost gave up on it, myself, and bought a used Multi Pro because of that.
Nowadays, except for the thrill of having a panoramic slice of a 6x7 slide from my Mamyia 7 scanned at 4800 dpi (*) on the Multi Pro with no sharpening (we all have our guilty pleasures...), I would happily live with the V700. Sometimes, I hate Epson for not providing an upgrade for the optics on the V700. That said, the Epson has trouble on multi-pass scanning, for instance, it's mechanics are not precise enough and you will sometimes get some ghosting...
(*) The Multi Pro can be used on a 4800 dpi mode, where the lens is changed and the FOV narrowed. Vuescan can use this to scan panoramas (ex: Xpan) at 4800 dpi on a narrow strip of the scanner. You just have to create your own mask: the negative has to be aligned with the middle of the holder and not the ridge. But I digress...
