In the March issue of Communique, Mike McGowan references that Tech Guide 3 is available from CORSA Merchandise. When I go to the site, I see coffer mugs, shirts and decals but no Tech Guides. The site I am going to is: http://www.corvair.org/csaindex.php?csaact=merch. So what am I missing and is there a better place to purchase the Tech Guides? Thanks Ed Orbea
