Besides those two companies, im not sure. I DO know that Canadian tire sells small stick welders for $100, and Lincoln Electric MIG's for $200 something. My father bought me a 110V Lincoln Electric stick welder from AirLiquide for $100 something. I have been having fun with it. It doesnt do too well with the real thin stuff like a MIG does, but I have been surprised with how well it welds the thick stuff. I just did some work today on my fathers bush-hog. Its pretty thick metal but the little bugger did the job so far.
