I bought a Solar mig welder years ago for $400.00 and it has done everything I've ever needed it to. It's a 110/220 volt 225 amp gas mig that uses a tank of argon gas for shielding. So much better then a flux core IMHO. Also, stick welders are great if all you plan to weld is heavy gauge steel; but if you plan on doing any sheetmetal work, mig or tig is the best way to go as they can weld both, to 1/4" and beyond. Mig is also the easiest to learn and use while tig is the hardest. They all take a little patience and practice, but it comes pretty quickly. Best of luck!
