Depends on what you are buying it for.
My first grinder was the 2x72 Grizzly. I sold enough knives built with that grinder to buy most all of the tools in my shop. I still use it most every day, even though I bought a KMG1 variable speed DC.
A few years after I got the Grizzly I added a pillow block setup for variable speed. The grizzly stays set up with a wheel and the KMG1 with the platen.
I bought 4 more of the Grizzly buffers that have that same 1 HP motor. Three are my buffers set up on a revolving table all set up with six different grits on the buffs. I keep the wheels covered with shower caps to prevent contamination between the grits. The fourth one powers my surface grinder.
Would do it all over again, just the same way, too :)
A lot of makers buy the more expensive brands of 2x72 and look down their noses at the Grizzly. Most who own one like and use them just fine.
My .02 worth :)
