Thanks Chem,
I'm just looking for a smaller light weight machine for certain things, I've been missing my Challenger lately, but can't afford a new one. Looks like I can get a 13 inch roto for around $400, It's 45 pounds so would be much ez- er to unload then the defender for the pre scrub, and much faster , better then the sebo.
Or I may get a 15 incher, if I can find one that's light weight.
