Thanks for the info Carl, but its a very long haul (expensive) phone
call from here (until I get Internet telephone working). I already
e-mailed INRAD and got enough data to make a snap decision. Now you
sold me on the idea and I plan to collect a few filters from them at
Dayton. They will offer a 10% discount, but of course I must pay the
Ohio tax, but no postage. And I have to get to Dayton ... But I
already paid the airfare; I was heading there anyway for my annual
overdose of sore feet and jet lag.

So now I can tell the XYL its your fault we are going to be short on
even more US dollar bills for our vacation in October. The good news
is that we already planned to fly to Las Vegas, so I can try to recoup
the loss in a casino ....
