I was debate on the forgelines and the BBS ones. went w/ forgelines in the end as I found a dealer to give me a killer deal. You can find BBS take offs for a bit less.
The was a place I contacted in NC that raced Porsches and vettes. they still ran 6-800 a wheel depending on specs. so you can save some coin.

any quality 3pc rim will cost a good penny. a car by the name of 'bad penny' has the forgelines.
Many racing Porsches use the BBS if you need to look at pics, however their bolt pattern is different and many run a single nut.
either way you cant go wrong as long as the wallet is able to release the funds.
Kinesis also has a few nice rims. K28 or K20 same price range 800-1200/ rim
