M.I.G/flux-corewelders are the only (feesable) way to go ! A relatively inexpensive one is small , yet powerful enough to to tackle most body project and even a lot of fabrication too.Flux-core is MIG minus the gas , it uses an innershielded wire to keep immpurities out of the welds whereas MIG uses a shielding Gas (CO2,Argon, or a mixture of the two ,25%/75%)
I would recommend going with a MIG set-up because you can use .023-.025 wire which is thinner and better for sheet metal. Flux-core is generally .030-.035 wire which will more than likely push through sheetmetal. Lincoln is a good company and their flux-core welders can easily be converted to MIG. You can get them from your local weld supply like Praxair or through a company like Eastwood, or even Home Depot. Weld-pak 100 $350 (flux-core) or MIG-pak 10 (same size and power as 100 but comes setup for MIG). Hope this overly long answer helps more than it confuses!!!
