'Ey, well you should also look into a lincoln electric. They high quality welders that get the job done right! Its a very small welder that can still deliver the heat. We use the 110 volt in my auto body shop. And it does the job well for auto repair.
They may have some deals going on, if not, you can still get a package deal. Although, you will need to buy the tank, etc.
Having quality for this, is important. You want to make sure you have a welder that can weld the thickness of metal your using!
As for learning how to weld, there is no way to understand it until you do it. Its all in the feeling, knowing the welder, and the metal. PM me if you ever need help on how to weld!
