I'm surprised no one has asked what it is that he will be welding.....
I've been using my old stick welder for 90% of the odd jobs around the house without too many issues. I only got a MIG recently and that was because I was doing more work on thinner stuff.
Only had to use gas when welding up car panels, otherwise I only need to use gasless wire. If most of the stuff you are welding is 3mm or thicker mild steel then just get a stick welder.
