Welder advice - where to start

I had never welded, but on advice from a few folks I avoided a 110, or any that could be switched 110 or 220. They said eventually I’ll want to do something the 110 can’t handle, and that the combo units aren’t as good in either mode as either dedicated units. I figured, no matter where I go I can get 220v. even if I have to make an adapter to plug into a stove or dryer outlet.
I choked up a little extra money and went with a Miller 220 mig & gas tank. Some may call it cheating, but the Miller has a auto current mode that you just set what wire size you are using, and the thickness of the metal. I tried at first not using the auto mode, but after a while, just gave up and put it in auto and it made life much easier for a beginner on sheet-metal.
