6-bit vs 8-bit? I'm not sure what that's referring to. I'd say, definately go down to a store (CompUSA, Best Buy, etc) and look at what's on display. The quality difference is huge. Some have horrible viewing angles (like, some of the lower-end models you have to sit right in front of or else the colors don't look right), some aren't very bright, etc. Go down to a store and pick out one that you really like and then check out prices online.
