I bought this last year. It didn't fit my shaft, and then I forgot about the damn thing and it's too late to return it.
I paid about $45 with shipping. I will sell it for $30 including shipping domestically (USA). I was going to put it on eBay but thought I would post here first in case anyone wanted to try this product at a discount. I can take PayPal.
