Hi Mike/Dunk,
Seyco website says the stands are from 25 inches to 31 inches in two inch increments. A friend of mine has his stand set up so that the front legs are shorter than the back, and the saw tilts forward. It looks a little odd, but it works well for him.
I found that even at the lowest setting the stand raised the saw too much for me to sit comfortably at it. I'm in the process of making a simple stand 20 inches high, which I hope will work OK.
You'll find the stand damps down vibration, and I put small rubber buffers between the stand and the concrete which damped the vibration even more.
I liked the crosses - simple and elegant.
Paul.
