I couldn't resist for $164... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3071319214&category=11223&sspagename=rvi:1:1 I got to try these out on a visit to Buffalo's Center for Computational Research last year, and it is amazing to see a pair actually pop up on eBay. Any cool tidbits about these? --- Matthew Haas Corning/Geneseo, NY
