Jim,

We at Williams International have gone through 2 that's two lasers per
year! We consider our selves lucky to have gotten close to the 4000 hour
mark on the latest laser. As for the $9000 per year utility bill make
sure that you check locally as we pay several times this per year! I
have heard of a few that went with the DuPont, Lyconix upgrade and are
very happy with it. In fact their excitement over the installation and
performance changes have prompted us to consider it as well. Please
don't ask who "they" are as I have been asked to keep that to my self
until they have gained more experience and time using the laser and
resin.

Steve,

Again, how do I ask my investors, after spending ~$500K 2 years
ago for the SLA-500 that is now worth less than half, for
another $100K? How dependable
is the solid state laser system? Are they more or less reliable?
 I have had no MAJOR problem, yet, with my SLA-5000, but I have
only had it since April. The SLA-500 is a different story, which
could fill a 100 page book and it was suppose to be a proven
machine!

Ok, lets figure this out!
$ 9,000 Utilities savings per year
$38,000 gas laser savings per 6000 hours? I currently have 6200
                 hours at 200mw at 59.3 amps and 15 months old. Is this
                  average?

~$47,000 savings 1st year?

$25,000 solid state laser cost? per 10,000 hours?
If solid state last 10,000 hours, the laser should last 1.5 to 2 yrs.

This looks good, but I have to wait and see.
