Melanie, so I did some checking of 8" grinders. The Rikon, Bauer, and delta variable speed grinders only go to 2000 RPM as their slowest setting, Whereas, the Rikon slow one speed grinder is 1750. Since I am a newbie to the sanders, would you still want the variable speed or go to the Slower one speed Rikon. What do you think of this Rikon buffer? https://www.woodcraft.com/products/8-low-speed-buffer?gclid=Cj0KCQiA-62tBhDSARIsAO7twbYDN8IdQ8saSMpthyUl6DYopdQTle6Wnq7H5tXrXgoHEVofWTyEeAcaAiafEALw_wcB&gclsrc=aw.ds
