Shoot, I've had my HF one for 5 years now. It ran nearly nonstop for about 3 months at one point when I was restoring my BOP a couple years ago. I've put all kinds of stuff through it over the years and would buy it again without a second guess if that time came. My only regret was I got the smaller one. I said I would get the bigger one when this thing dies but it just keeps going. I want to say it was only $50 too after the normal HF coupon. Maybe I just got lucky.

OP - If you like your tumbler and would rather just replace the motor, they are fairly cheap. The part number would most likely be on it but they are basically the same thing as what all those blow up Christmas ornaments are in peoples front yards. At least the one in my HF unit is. Was an exact match of my M&M decoration
