I saw several of the $40 ones that didn't have the slotted wheel, but is seems most are 2.5HP and 18+ amps, way too much, so I might bid on one of the 1 to 1.25HP versions, one looked as if it was ball bearings rather than sleeves, better IMO. And a $20 bill, but what controller? Fans I have, but they only cool the outside, that built in one sucks thru, which considering the damages one can do to the PM's with what could be called reasonable heating, I think I'd arrange a small cover of some kind around the brush end of it and have a muffin sucking or blowing thru the motor. Again, that depends on how much room has been cut away for it under the bed. Which isn't much. More than likely a new pivot mount will need to be made behind the bed, and additional metal removal for the passage of the drive belt at the more rearward location. >From looking at the existing JT250 controller, I get the impression that with more access to cooling than it gets where it is, 5-7 amps might be doable. Probably more dependent on those ceramic resistors than on the solid state devices if they aren't sweepings from the Fairchild floor that is. I am not allergic to moving all that to a bigger box "out back". And I just found a 1 HP version that claims its all there, controller and all, so I made the first bid. Since its so low powered compared to most, that might even be the Buy It Now price, but he didn't show one. :) Now, if paypal isn't screwing the moose again, I'll have something to play with thats considerably stronger than the existing one & might even fit. Paypal screwed me over good on my last attempt to buy something, bastards reset my password and refused to send me a password reset message. I had to sneak thru their humanless answering service, and get abusive in order to get a pw reset message from those paranoid MF's.
