"I then found that Grindmasters use crushing burrs where Bunn uses cutting 
Ed, just curious where you got this information.  It's been a while since I 
looked into grinders, but in the past, Bunn grinders were all made by 
Grindmaster here in Louisville and were no different than other Grindmaster 
and rebranded grinders made by Grindmaster.  Things may have changed, but 
this is the first I've ever heard of a 'crushing grinder' except for the big 
industrial roller grinders.
What would a crushing grinder burr look like? vs. a cutting burr?  I've only 
seen the cutting burrs, flat and conical.  Of course the cheapie Walmart 
burr grinders are not sharp and pretty much crush more than cut, but we're 
not talking about those.
