Which Mig welder to buy?

I have had a Miller 180 for over a decad.it has seen heavy daily use and now weekend work. It has not once been in for service and had hundreds of pounds of aluminum and steet through it.
Now I am in the tig market. The Everlast style brandzs are tempting but I think I will be going blue again.
Welders are the one item I can truly say you get what you pay for. Dont waste your time with 120v unless thats is your only option.
