As mentioned, it all depends upon the type of work one wants to do. I started out with Oxy-Acetylene tanks and later on, a Lincoln 225 AC (Tombstone) welder. It was good practice. If I had to start nowadays, I'd still get the O-A tanks and torches but I'd start out with a 120V MIG, either a Lincoln, Miller or Hobart, e.g.
The O-A tanks are great for cutting until you can afford a plasma cutter and the MIG will do most smaller fab. projects. With a CO2 tank and a jar of welding gel, you can do some awfully nice work. I found MIG very easy to get going with.
