I personally have a Delta Universal Wet/Dry Grinder Model No. 23-700.
Small fast wheel I never use, I love it for the large slow vertical wet
wheel.  It's slow but everything I need.

Here at school I've been slowly rehabilitating a pile of old abused
footprint chisels on the schools Tormek.  After 15+ years with the Delta,
comparing them head to head, the Tormek is nice enough, but for a lot more
money. Of course it has all the profile wheels the Delta does not, and I'm
eager to use them once I have time to start turning again... So, my opinion
may change.
