SD, I'd have to say you are getting a real good deal for the money as long as they arn't hot. I run a Big40 deluxe bought last year bottom line on the machine after taxes not including spool guns, suit case etc. Was $13900.00 with cat deisel. Check the arc stability as there are some that don't follow duty cycles while gaugeing. This is the second big40 I've owned and always been happy with there performance.
