For "starters", consider going to school.   I think the class I took cost 
$300 a quarter but gave me hands on instruction on stick, gas, mig, and tig.
Also instruction on using cutting torches, carbon arc, and plasma.  This 
class also gave me access to a press brake, shears, ironworker, sheet metal 
tools,
and so on.  It gets you hooked up with local people who are metal 
workers.  You'll be welding or learning 5 hours a week which will help you 
get in the
time needed to learn.  Trust me, it's not the equipment that makes you a 
weldor, it's your skill with the equipment you have available.  It takes 
time and
it really helps to have someone at your side to observe and teach.

Another recommendation is to buy one of the major brands; Lincoln, Miller, 
Hobart are the standards and someone here will probably recommend HTF.
By buying a major brand, you develop a relationship with your local dealer, 
some are better than others, but it's one more ?expert? to consult.

I started with gas, moved to tig, tried stick, and finally mig.  I'm still 
not a skilled weldor, but in using all these processes, I've come to really 
appreciate gas.
Gas will cut, weld, braze, and form a variety of metals.  You can vary the 
heat by changing torch position.  Gas also can be used as a "hot 
wrench".  Your mig is not as versatile.  There is a TestaRossa being 
restored for Pebble Beach here in the Northwest.  It will all be done with 
gas.  The steel tube frame will be gas welded for authenticity, but the 
aluminum body is also being fabricated with gas. They use gas on sheet 
metal because they can anneal the metal which allows them to use hammers on 
softer welds rather than grind on the harder weld of the mig.

I wouldn't choose sheet metal for my first project.  If you're thinking 
rust repair, I'm thinking you're going to see some holes.  I've certainly 
seen more than my share.  I have one new fender on my pickup because I 
thought I could repair a rusty one.

The above is my opinion, your experience WILL be different.  The only thing 
I'd be sure to do is to talk to people in your area who are knowledgeable 
and observe the welding process in person.  One of the dealers I visit has 
a MIG welding station all set up and ready to try for anyone who walks 
in.  Book learning is helpful, welding is ultimately hands-on.  The more 
experience you have will make your choice easier.
