Yeah you probably can get the basic part cheaper, but I feel that Jody Collier does a great job at Weldingtipsandtricks.com and should be supported. He is a weldor's college degree for free via internet video.
His Tigfinger is one of the ways he supports the bandwidth and production costs. Buying a few things from him helps keep him making videos and answering questions. I don't know of too many folks with as much welding knowledge as Jody.
