I would pick neither.
I got a Quote for Genuine Hayashi Streets brand new, inc Centre Caps and it was <2k (will find the exact price) to my door in 14 x 8 and 14 x 9 in type ST, this was less than 3 months ago.
I can understand if you are on a budget - If the above is out of your price range, then so be it.. I would pick the Knockoff Hayashi's.
Have you had a look on Otomoto's Website ? or done any searching on Yahoo as to what used wheels you can find ?
