Suitcase extreme

by Orlando
(Dallas, Texas)

We have three miller machines, the syncrowave 250 dx for the shop, a millermatic 135 for mostly migging mild steel and some basic stainless work. I just recently purchased a 302 trailblazer for our field work. I need to know if the suitcase extreme is worth the purchase and can we use it as an aluminum wirefeeder as well as mild or stainless steel?
