I'm using a VP930B right now. Overall, very nice.
About the only thing I can knock it for is that it has bad ghosting/smearing on dark, low-contrast dark->light color transitions (so if something, say, dark grey is moving over something that is black, the black will appear to 'smear' over the grey). But that's sort of worst-case for almost all LCDs in terms of ghosting. If you never ever want to see any ghosting, this is not the best LCD. But the color and contrast are great once it's calibrated, and in other situations ghosting is quite minimal.
I posted a long thread right after I got this monitor; if you search you can probably find it (I also looked at a Dell 2405FPW but ended up not keeping it... just too much cash at the time, and I decided I preferred dual monitors.)
