Here's the scoop....
You'll find that most (if not all) of the "turbobuick" vendors sell the ScanMaster. It is one of those useful tools that every owner should have.
You'll also find that every place will have them for the same price...within a few bucks.
So....whether you go to Ramchargers or Poston's or Kirbans or John' Performance or Cotton's you pay the same....
BTW...all of the above mentioned vendors are the "Good Guys"
Or you could wait for a good used one to come up for sale.
