welding???

[McC_65_91]

Im pretty new to this, building my first project here. A 65 GMC k1000, not a frame off resto, but i would like to try and do the body work myself, as well as some other welding projects around the house.
Ive done a little welding before but dont have my own. Does anybody have suggestions on buying a arc welder. I dont need top of the line and i wont be using it for anything real heavy. I would be willing to buy used and open to really any suggestions
