I bought my first kit from Staton on ebay. It was a 1.6hp Subaru friction drive, and I got a great price on shipping. There was absolutely nothing wrong in the kit, no scratches, no dings.
I have both friction and chain drive. The Mits 2.2hp engine with roller drive is my favorite, because it's easy to remove/reinstall the engine or entire system. Besides, the chain drive won't fit my cruiser bike.(Sigh)
