I seldom buy from Amazon, but they're a good reality check price wise. I'm not above printing the page and asking a dealer to meet or beat their price. Works.
I got the Hobart and I love it. I've only been practicing and doing little stuff with it, but it makes my lack of skill look good.
With any welder you get, you're gonna spend more than just the purchase price. You're gonna want a good auto-darkening hood, some good gloves, maybe a cart, welding pliers, some different size wire........
