HUO is very much bullshit. I own one that is and yeah some aspects of it are pretty nice, but its not perfect. I have seen newer sterns that are 1 owner machines, but they have scuffs from moving and insert wear from raised inserts. I have seen lightly routed machines that you couldn't find a flaw on. I have seen machines with unknown providence that looked new. End of the day, HUO means absolutely jack shit.
Buy off condition, not off acronyms.
