24bit colour TFTs

Do these actually exist at a reasonable price point yet?

I'm still waiting to upgrade the CRT. Main usage is game development so while a good response time is helpful it doesn't need to be ultra quick - equivalent of about 8-12ms TN display would be good - the colours have to be there.

I tried a really great TN display - it was fantastically crisp, great contrast and looked fab.. but the colours weren't there and the banding annoyed me.

Size doesn't matter - prefer 17" if possible for cost reasons.
