From my phone call, the guy said that make at least 3 units. I
would expect $100 for 3 from the one guy I spoke to. I know there
are others as well.

When I was looking at getting pcb cutters, I was been quotes $50.00
for the first one, three for about $75

I'd be more than happy to get a few and split the costs between those
who wanted to get one.

Do you have a source for belts ? I think that would be the first
step to agree on. I would go for more power as my first choice, but
have only looked at trapezoid so far.

I'm sure I can get the specs so that would not be a problem.
