I've got the eastwood gun and it's good for the price. Professional guns are much more versatile and also much more expensive. There aren't many mid-range choices. I've done rims, bronco parts, tumblers, wagon parts etc. Biggest issue is size of your oven and the fact that you need a separate oven. You don't want to bake bronco parts and eat out of the same oven. Having a good ground and fresh powder will increase your chances of a nice finish.
