The only upside to flux core is that you don't need gas most of the time.

Miller makes a good machine. Also get a good cart that will hold a gas bottle. If you don't get a good cart. You will be kicking yourself later, and hating the cart.

Gas bottles. I have 3 that I lease for 5 years at a time. CO2 for carbon steel, Tri Mix for stainless steel, and Argon for aluminum. You can buy the bottles out right if you want to. But if the bottle or valve goes bad. You're stuck with it.
