I was wanting to get a few opinions on which of these blade grinders you guys prefer. If you have a Neary 440 model (which is the one im leaning towards) or the Wall BG 121 let me know what you think about them. I can get either one for about $450 but cant decide which one to get. I would consider the Mag 9000 if it is head and shoulders above the Neary and Wall. I will be using it on 48" and 60" mower blades mostly. Ive got a bunch of guys wanting me to sharpen for them if I get it so speed will be a concern. And NO I wont be buying the Mag 8000 $1000 dollar grinder so lets nip that in the bud now Thanks guys.
