I was really looking to only spend 400-500 originally. But that was for the 70-150 lb range. I never really set a full budget though, I've mostly just been looking at price/lb. I've got most of my tools(half a dozen hammers, tongs, and files, HF belt/circ sander, angle grinder) and a good stock of scrap, I just have to get a forge and an anvil.
The same guy is also selling a 2x72 grinder, and I thought about trying to haggle by buying both, but I'm not really sure the grinder is worth it right now. He's asking 900 for it. I do eventually want one though, so I'm still considering it.
I do like the Bank of Iron thought of it. It's still a decent chunk of change to throw in the Bank of Iron though lol.
