That's essentially the conclusion I came to. They were roughly equal or the medium format scans may have been slightly better. That's with a v500 that I paid $150 for. You have to do a ridiculous amount of sharpening to get a decent scan out of them. The V700 is better in this regard, but still only offers about 2000-2400 DPI of real usable resolution. If you don't do very large enlargements then resolution isn't as important. I got good 8x10s out of my V500 and passable prints up to 16x20 as long as you stay 2 feet+ away. If you're coming from a dedicated film scanner, then you'll likely be disappointed with consumer flatbeds. That's just my experience, so your mileage may vary.
If it were me, I'd sell the 35mm scanner and maybe some 35mm gear and put that towards a scanner that can scan both formats. What is your current film scanner? I didn't loose more than $50.00 when I sold my Nikon 4000. They retain their value very well. You could then pick up a used Nikon 8000 or 9000 or maybe a Minolta Multi Pro.
After looking for awhile I was able to pick up my Creo Eversmart Jazz+ and a G4 to run it for $1000. I had to drive out of state to get it and it takes two people to carry, but it's worth it. It retailed for ~$17,000 when it was new. You can find old prepress scanners like mine on craigslist all the time if you want to go that route. Just be aware that repair costs and software can be through the roof, so you need to make sure it includes everything and is in perfect working order. Models to look for are Fuji Finescan or Lanovia, Creo/Scitex Eversmarts, and Screen Cezanne Elites. Eversmart's are the easiest to find and parts are more widely available.
Refurbished pre-press scanners There are better deals to be had, but you can download brochures here and get an idea of what maximum going rates for these scanner are.
Anyway, just something to think about.
Edit: I see you're located in New York. You're sitting on a hotbed of old pre-press houses. My scanner originally came from the New York area. It shouldn't be too hard to find one at a good price if you look.
