Farside,
The VP192B is the most recommended LCD right now for gaming because it has a very fast response time of 12ms, compared to other LCDs that average around 25ms. The lower response time is integral to getting rid of the ghosting. I think some other company makes an 8ms LCD now, but it is only available in 17" (Samsung?). I'm planning on getting the VP192B for myself too, maybe even two of them.
If you are tight on cash you can get the slightly cheaper VP191b ($100 less) that has a reponse time of 16ms, which will probably do fine for trading and watching DVDs, but it is not fast enough for first person action games. This model also has a better contrast ratio of 700:1 compared to the 92's 450:1, which means that the whites and blacks look better.

Trying to recall from memory, you might want to check out the VP191s, as well. Specs are apparently faster than the 191b.
