Pimp My Wheels?

[9hellheaven]

Just having a looksie on ebay under wheels/tyres 997. A company selling what look (thats look) to be nice wheels in black and or silver for 899.00 a set. Are they crap? Or worth a look? Not sure how after markets hit the warranty either. Is it a case of you get what you pay for..ie need to cough up 3k for a nice set??
Thanks 9HH.
