I have a self contained Hobart plasma cutter at the that I use occasionally. It needs low humidity because it has no air dryer. And I guess I am spoiled by the large Miller we have at the shop. There it is a must because we work a lot of aluminum. I bought the small one with the idea of using it to cut out rustouts, but I find myself bringing a nibbler and small reciprocating saw home from the shop and not worrying about warping anything. The plasma cutter I have at home is one of the few things that I really could live without.
The Hobart 140 welder I have at home is a different story. I use it a lot. I use Argon/CO2 mix on everything. We have welders up to a Trailblazer 440 at the shop, which is on a trailer, but I have never found the need for anything larger than the 140 on a car or pickup.
As for Eastwood, my opinion of them is they sell junk that makes the job look easy and then when the sucker gets it home, it doesn't work at all.
