Is there a general concensus as to a good grinder - standard 2 wheel type? I'm
looking for something sturdy. Voltage and phase requirements aren't a problem.
TIA.

My local machinist's supply has a small used Diehl grinder. The bearings
were unbelievably smooth. Thing just kept on running after being unplugged,
virtually noiseless.

The intended use should dictate. In my mind's eye I can see a large
grinder, three phase, 12" wheels, 2" wide. Great for a weld shop, not so
good for a machine shop, where you might want to sharpen lathe tools. My
personal choice for sharpening lathe tools is a grinder mounted about chest
height with no work rests. That wouldn't be worth a damn for a weld shop.

That's what I have in my shop, why is it not so good for sharpening lathe
tools?

All depends on the nature of the wheels and how they're maintained. If you
use the wheels for rough grinding, I doubt you'd have a surface flat enough
and smooth running enough to be very successful at sharpening toolbits. The
grain size may be a bit coarse, and the wheel too hard for toolbits, too.
A soft(er) bond is very desirable for grinding HSS, unlike low carbon
steels, where a harder bond is more desirable. Certainly nothing wrong
with your choice otherwise. My point is if a guy is going to sharpen
toolbits, a smaller grinder makes more sense. If he's going to do heavy
duty grinding (weld shop), a smaller grinder makes no sense. Better too
large than too small, though. Just match the wheels to the job. You need
a basic understanding of wheels in order to do that.
