For a good 110v machine a miller 135 with gas. .023 wire.
Auto darkening hood of your choice. I like the miller classic because it's around 90.00 buck and instead of fancy watch batteries it takes AA. Get a hat with that and ear plugs. Nothing more bothersome than a hot bb going in your ear or melting some hair. Good clean safety glasses. I like flat lenses with side shields because curved plastic tends to distort your view. I'm hard of seeing so I use cheaters (magnifiers). Being able to see the puddle in all it's glory tells you a lot about what's happening and where.
A lot of guys don't cover up. Sure welding in short sleeves is manly but the hot bbs aren't what's dangerous it's the UV. Think skin cancer.
You'll probably want a good pair of welded pliers, extra tips, a wire wheel or two, maybe a good 5" grinder/sander. Different gloves. I only use the thick ones for dual shield now...
So yeah a good gas welder and safety equipment. Can't think of much more except chunks of metal to practice on. Pull the trigger and move
