I have 6 of them, they are the Buyers version of the Meyers model 36000. It has a 600lb capacity hopper. The motor is about $200.00 and needs to be replaced about every 3 years. Make sure you use lots of never seize when you put it together with the new motor and that way it will be easier to take apart next time you have to replace the motor. The spinner/auger assembly rarely needs replacement, but it is about $150 for the setup. Esentially you amortise the cost of the $200 motor over three years and the spreader will cost you about $65 per year to use (after you put the initial new motor and auger/spinner assembly into it to get it back up to factory specs). They are very dependable and will pretty much last forever. The motors need replacement every three years because they are out in the open and are upside down so the weather and salt eventually get "sucked into" the motors.
Hope that helps...
