I also bought an Aluminum spool gun for my mig. Let me tell you this.... It's all thumbs up for this one. I have no problems with my wire feeding and weilds are smooth. I'm currently here in Canada (BC) and had to pay $268 and some change for the kit. If I was back in Texas or my other home in Wash. St. I would have payed a lot less. The kit came with a wiring harness (took about 15 min to install), gun, roll of Al wire, 5 tips and a manual in a nice plastic case. Worth EVERY CENT. Made some Al repair welds yesterday with it... NICE!
