Thanks,
I didn't phrase that too well. I'm familiar with the sprockets, just wasn't too sure about the vendor. I placed an order anyway. He was very quick to respond via e-mail... so far so good.
I had great luck with them. I wanted a 50 tooth and they were out at the time and let me know immediately and gave me a few options. I really wanted the 50 and told them I would wait for it.
When the sprockets showed up they had thrown in their sprocket bolt kit along with a note thanking me for my patience.
I bought a set of IM sprockets and an oring chain from them because they had the best price. When I got my shipment, I found an xring chain and a note explaining that they were out of oring at that time and he upgraded me to the xring. Pretty cool. Great service.
