I have an opportunity to pick up a used splitter. It's a 6 yr old Northern Tool 20T with a 5.5 hp Honda motor Horiz/Vert. operation. In good physical condition and with less than 100 hrs on the motor according to the owner. Any caveats on this brand/model? Anything in particular I should be looking into? The asking price is $695 which is more than the DR electric 6T I had been considering. Does anyone know what this was selling for 6 yrs ago?
