what is the least expensive welder i can get away with ?

I have a Hobart Handler. The few times I have used it I liked it. It is a name brand that didn't bust the bank. I have yet to get a bottle for it but I will eventually. I think Eastwoods brand are just rebranded Hobarts from looking at them. IMO I would stay away from the Harbor Freight types. As stated check CL, E-bag and your local pawn shops for a good used one. Just do a good going over before purchase of a used one.
