We have a 2 model 406 units (one we only ran once - we used to sell them).
We are looking to sell them. We also have a 400. All were demo machines and
barely used.

Hi Bill,

The Z310 and 810 (if you can get one) are great for IC work. It cant compete
with quickcast for accuracy and min wall section, but has other redeeming
qualities, relative to what type of casting you are making.
There was a paper (mine) on the topic in the TCT conference procedings from
this year if you're interested in more info.
