I prefer an 8 inch slow speed grinder. The one woodcraft sells works great. Pretty much the same price and if you catch free shipping makes it better. So in my opinion "not for me".
Woodcraft.com has a 2 speed grinder on clearance for $99.99 with free shipping, (I believe-I could be wrong). My local WC does not have any left but you might check if you have one local. I have the slow speed and I have not had any problems with it.
