I already have a buzz box, so I don't see me using the mig to build a bumper or whatever. I want it for the body work and little dinky things that go with fabbin. I have heard alot about the mig being a better looking weld, what truth is there to this? I also am curios about strenght issues. I know with a mig that you can get strong welds, but is it eisier to just arc it for the penatraition?
