What I did while waiting for those swap meets was purchase the aforementioned hammer and dolly set from HF. It gives you something to practice with. Martin is the go-to company for hammers. I use all different shapes and sizes of dollies out of repurposed steel, train rails, whatever I can find with odd shapes. Then there is the Hardy Hole in the Anvil that accepts 3/4" squares that you can weld all sorts of shapes on.
