Champ
Blue Line Champ is a great machine!
We have one in our fleet and it runs consistently without down time. We have been ruining it for 13 months now.
It gets really hot and has plenty of vacuum. If you are looking for a machine for residential and some commercial you can't go wrong. I think it is a well built machine and think that you will truly enjoy your purchase. If I was in your shoes and there was a great deal on a Champ
I would jump on it because I used to work a DIST. and they didn't sit around for full price. I can only think of one time when we had one on sale(customer stiffed us) I sold it in less than a week.
As far as support goes, Scott Harlib is great and they stand behind there product...
