 From the MP list (http://mailman.qth.net/mailman/listinfo/1000mp):

Chris SVL again:

Their website http://www.qth.com/inrad currently says "delivery starting 
the last week of September. Units will be shipped in the order in which 
orders are received."  Someone on the MP list said Inrad had been 
holding back to wait for customer reactions on the first batch that was 
released around Dayton-time... seems fair enough.

Has anyone been able to access the pdf about roofing filters from teh 
Inrad site?
