I got mne second hand, but I believe it was from Unique Autosports. Caz sells the GFB ones, sposed to be very similar to the Unorthodox ones. I'd keep away from the ebay ones, remember seeing some that had the timing marks in the wrong spot
retro zx I would stay away from $50 UDP's. Anything that spins needs to be balanced and well made or it will cause problems. As far as UDP's go stick with Unorthodox Racing or GFB, both are proven quality products.
