Need new monitor - seen Apple 20" @ £260 - good idea?

Hi everyone

I am on the look out for a new monitor and need your recommendations. I'll be using it mostly for gaming, internet etc, and maybe the odd design job hear and there.

I've seen new Apple 20" cinema displays go on ebay for as low as £260. I know Apple tend to overprice a lot of things but £260 when they retail at £399 seems very tempting.

So from what I've seen these monitors look great but are there better out there and possibly cheaper?

Thanks for your help.
