RWR
I don't believe that I've ever heard anyting bad about the RWR stage 1 kit from anyone, so you should feel pretty safe to pick one up & not waste your money. Some other shops who sell power modifications are having much worse and more costly results with little to no reliability. RWR has had this kit perfected since probably 2000, so you don't have to worry about being a guena pig.
