Everything Josh said in the above post is 100% correct. Granted the 6 speeds dont need an rps c/c or a tilton but still it gets expensive no matter what route you take.

And as for the ebay ad being high. I believe that particular one was a scam as there have been hundreds of scams with supras on ebay recently and therefore many supra owners are automatically bidding high so nobody gets screwed or having the scam pulled off of ebay.
