I really like the Judson, Cobb and Dwayne machines. They keep it simple like a old time muscle car. Something we all can easily work on and get parts for locally. I see these new Prochems, HM and so on and its just like a new car, you gotta damn near take the thing apart just to fix it, or it has so many little parts that can go wrong on them which in turn cost a lot of money to fix with labor.
All TM are just an engine powering a blower and a pump.. sometimes a heat exchanger. I would like to see a Judson with a quality heat exchanger.. that would be kewl.
