Like colby said, this will cost you a lot less than doing your own unless you do all your own machine work, aka the port work, and so on. I do all my own port work and im a dealer with pretty much every product you can think of, so i could save some money. But if you dont do all your own work, this is the way to go, badman gets some pretty damn good reviews around here. i'd take him up on it if i was you.
