In response to Ed T- I have to disagree that this unit is "almost obsolete". For smaller end users these older trucks really fit the bill as they are non- electronic (therefore easy to work on & less expensive too) & parts availability is not a problem as of yet. I work on a number of these in little machine shops, beer distributors, etc & they work out great. I must agree however that if the intended use is a full 8 hr work day this may not be the best choice.
