Ordered via the eBay store for $375, and got a call from James (the owner) not 5 minutes later asking about my build and TJ set up. He had the shaft built and shipped out THAT day, which just so happened to be New Years Eve!
Easy install with 2 local club guys, and the shaft seems great so far. I never really drive over 2,500 RPMs so I can't comment on how well balanced it is over 3k, but so far it's doing perfectly.
Just wish they had better stickers
