i've heard that term also ,so i knew what you were talking about.how often will you use it? do you need air assist?i bought mine second hand several yrs ago.and only verly rarely use it.so i say ask yourself these questions ,read thru the responses again and make your decision.they can take up alot of floor space i would consider a folding unit if i had a small shop.mine is actually going in another building when i get my motor back in...............dave
