my personal favorite for small wire feed welders is the Millermatic line by Miller. The Millermatic 135 is 110v and I think around $400-$500. I have a Millermatic 175 (220v) that I paid $675 for. It has definitely earned it's keep. You can study them on the miller website. Note: Miller is owned by Hobart, they sell a Hobart handler 135 and a Hobart handler 175, you can buy these at places like TSC, the prices are comparable to the miller, but the Miller is of much better quality. so, for the same money, buy the miller.
Also..... flux core wire (gasless mig) does work, but there is no substitute for regular mig welding, but you do have to buy a gas bottle.
