I have a Maxx470 2 yrs old with 1550 hours on it. It has been faultless !.
Never ever put a foot wrong, this is my 2nd Maxx 470 and I would have
one in a flash again over any other make of slide in.
Last week I added a
Boxxer 427, although I have only yet put 12 hours
on it, it has awesome !. 245f heat with a HM TM 06 wand constantly
flowing and excellent vac. Your better off with the liquid cooled motors
as opposed to air cooled, they last longer and provide more heat.
Have you considered the Maxx 450 diesel, or the new Maxx 470
Turbo diesel ?.
Oh, one other good thing about the
Boxxer 427 is it's very easy to
work on, everything is very accessible.
