I believe you could say the same for many pre-owned units from smaller private companies too. As for the several Aplundh units that I looked over beore purchasing, some were better than others, but non were horrific, and they all passed current safety and di-electric tests. I paid $14500 for mine, and I'll be damned if you show be a better value for what I paid anywhere else.
My truck went into immediate service, and as far as the boom and hydros are concerned, I have had zero issues, as a matter of fact the unit just passed its second safety cert with no upkeep/replacing parts other than grease. The truck itself got new brakes and a clutch, but thats wear and tear stuff that just lets go after a while.
Don't make blanket statements about equipment procured from one area or another, that just makes you sound biased, uneducated, and frankly, just like a salesman. I know of the info I speak of from first hand experience, not some "friend who used to work for asplundh" so argue what you want, but I know.
I've seen joke units at joke prices, that I'd put my ####ty abused asplundh truck up against all week long. Bottom line is, most of all you salesman, find garbage whether it's from asplundh or whomever, shoot them with white paint, and call them something they aren't.
