I had a Weston 5000rpm arrow saw that worked great for well over a decade......until it quit one day last fall. I tried to contact Weston for a replacement motor, but that ended up a fruitless mission. Then I looked on Ebay for replacement motors, but all had different sized shafts for the cutting wheel. So after shopping and comparing, I bought an "X-Spot" or Decut from Lancaster just before Christmas. Every month or so, Lancaster has a free shipping offer and you can save if you pay attention.
I haven't used it yet because I also cut carbon arrows outside on a calm day rather than pay for a vacuum attachment and risk having carbon dust indoors. However it appears to be a solid unit for the money.....hopefully worth the investment.
