For Aluminium, I agree wholeheartedly, a TIG makes it realtively painless.

The other issue I found with MIG is that the welding material begins to come out as soon as you pull the trigger, and you have to be ready to handle it.
The outcome has functioned quite OK I must say.
After practising with a friend's TIG, I bought my own, and have had much better results. I would call TIG the 'gentlemans' welder. It is not fast, and probably more expensive to run, but I find the results far superior. The area to be welded is heated with a plasma, then filler rod is applied as and when required. (Unlike MIG which spurts out wire whenever trigger is on)
I am self-taught, and would probably improve with some formal training, but managed the TIG quite OK with a bit of help from the Web.
My vote is for TIG
