Dormant hero!!
Pretty cheap ones at home depot will get you started
Wheel grinder sounds way better than an angle grinder?
I need one of those and a serious vice in my shop...

I bought mine in San Francisco too.
There are different models and sizes and some can pivot around if you think you need that. A good way to mount a vise is to have it sit on a metal plate so it sticks out a little from the bench. The bench doesn't interfere with things and you aren't pressed up right against it. Need a sturdy bench though, possibly attached to the wall. I used an inch thick aluminum plate and drilled it for attaching the vise and then holes for bolts through the bench. http://www.wiltontools.com/us/en/products/ Mine has the enclosed thread, i guess it's the machinist's model. Been using it a long time, flip the handle and it makes two or three revolutions on it's own, but no slop in the jaws.
