Sprocket Options

I thought I would start a thread on the different sprocket and mounting option sources....Aside from the kit style stamped sprocket who else out there makes a quality sprocket ?

There is the M.M. hub adapter and sprocket

FireBelly Cycles sells a disc brake mount adapter and sprockets

Kings Sales sells a disc brake adapter and different sprockets

Anyone else have sources for good sprockets and mounts ????
