While I agree with Fred that MIG is easy to set up, one of the (many) reasons I use the TIG instead of the MIG is that I don't have to change wire spools when switching from stainless to steel to aluminum. I can just turn on the machine and grab whatever rod I need and go. If I have a job suitable for the MIG and I see I need to change reels, I get the TIG.

MIGs great for big work and production (doing lots of frames?)

Downside on TIG, three cables instead of two and they like to get all tangled (unless you have the heat control in the torch).
