All I can speak from experience on is the Grizzly. It's a good grinder if you're somewhat handy.
Although mine is as it was when I bought it, but I haven't gotten really serious with it as yet and maybe never will, I have been satisfied with it mostly.
My Grizzly does what I want it to except for changeing speeds. Some guys have modified theirs, I understand, to correct this, but I don't know what all they've done, more about this below.
That would be a huge plus for the Grizzly!!!!!!!
I think the Grizzly is one helluva grinder for the money and I especially like the through shaft that you can mount a buffing wheel or other device on the opposite side.
I have mine set up with a heavy & coarse buffing pad, and my Grizzly buffer, not enough horsepower, set up for finish buffing.
I also bought the set of videos that Allen Blade made, took me forever and some nasty threats to finally get them, and have been so disgusted with him since I haven't looked at them.

:grumpy:
But Allen is one helluva knife maker and those that have his knives swear by them.
The pix I have seen of Allen's knives show outstanding work so whatever he did to his Grizzly must have worked.
The videos show the tweaking that Allen did on his Grizzly which I think he uses primarily to make his blades. They also show some tips and methods of grinding the different grinds such as convex, hollow and flat ground blades I understand.
These are supposed to be some really kick ass videos, I'll get around and watch them one day when I'm feeling froggy again.

I have too many irons in the fire as it is. Discovered the other week that my router table and fence had warped so I need to repair that before I can make anymore Flutes.
It's always something it seems.
