2 schools of thought.
First, though, no matter what people suggest there will always be "the other side". If you haven't figured out what those replys/who they originate from yet you will in due time.
1st school of thought - go old school with a transformer based stick machine. I would get one that does DC also, not just AC. DC makes a difference. Good transformer welders are like ****roaches. The world could blow up and there would be 2 things left - ****roaches and transformer welders. They are tanks, but are going to "be there" when anything else goes down - so they have their purpose, even today.
2nd school of thought - go with a modern import inverter machine. They are relatively cheap and still can weld pretty good.
If you go the 2nd school of thought route - I would throw out there Everlast. The PowerArc 210STL is the best bang for the buck there - it is even a capable DC TIG machine if you want to upgrade and try TIG. Otherwise, what you get in the machine for the size, weight, and price you can't beat it. It is a DC-only machine, though (steels on TIG - carbon and stainless, no alums or alloys - need AC for that).
Good luck!
