Keep an eye on industrial surplus sales sites, as well as Ebay. Remember, you don't need one marketed for automotive use. There are many industrial units which, in many ways are even superior. And you can stumble across them for a steal sometimes, because racers and engine builders are not aware of them.... I got a nice Krautkramer Branson Unit (pretty much
the Gold standard brand for industrial UT thickness ) for $125!!!! And yes, you don't want anything to do with a Made in China one...
Also, you have a PM
