I have the V750, the predecessor to the improved (I would think) V850, and have always been very pleased with the excellent results it gives. The only criticism of the V750 would be that the negative/transparency holders are a bit on the flimsy side, worth checking to see if they might have been improved on the V850. I can't however help with a comparison with the V600.
i recently read an article, which I don't have handy, that the neg holders are better on the 800 series. The writer said he bought the set of 800 holders to use on his 700 scanner. He claims they hold the negative strips flatter than the old ones did.
