How do the Groz engineer's squares measure up for setting up a TS, BS, etc?
Rockler has them (set of 3) on sale for $29.99 instead of $39.99.

I found that a nice 4" double square is a pleasure to use, and very handy.
They usually go for $40, but I've seen sales for $20.

I use that more than a fixed engineering square.
