What's the best pick for my first welder?

I bought mine because my cousin works for a welding company. In talking to him, I found out his company used to sell these Eastwood units. He’s a helluva welder and said for the money, they are hard to beat, price wise. I bought it mostly for sheet metal on my Duster, but have welded heavier gauge too. If it gets real crazy, my dad has a stick arc welder and I have a friend with a high amp mig/tig welder
Yeah I know a few people with arc units, but mostly along the lines of fixing horsr trailers and fixing tractor parts (my friend has an arc welder but the house he moved into isn't wired for 240). Looking for something than can do autobody/sheet metal, and some heavier stuff too if possible
