I had the same questions and issues. If you're not going to do too much, then the Harbor Freight is the ones you want to get. I got the 220 volt 120 amp welder, and it does more then I need it to.
here is my welder. It might be overkill.
This one is a little cheaper, and it only needs the normal wall outlet (110 Volt). It's fine for normal use. I only used mine once, and that's pretty crazy, I paid 200 bucks for one single use. This one (if you wait) you can get it for 89 bucks. Just be patient.
the cheaper one
