It took me a while to realize this but there are two companies making Aliens these days: Fixe and Totem Cams.
You can get the Fixe cams at Rock & Snow for $80. They have Blue, Green, Yellow, Gray and Red.http://www.techrock.es/index.php?mmod=shoptr03&file=list&cID=2
Totem Basic Cams are pretty much only available online for $60 with free shipping to the US (and 10% off if you order 5 or more). They have Green, Yellow, Red plus two Hybrid sizes. http://totemcams.com/catalogue/index.php?id=1&f=2
It's been hypothesized that Totem can sell them cheaper since there's no middleman. Of course, pricing & mfr cost don't always go hand in hand, take cell phones or the Xbox. Sometimes pricing is set to drive demand or to drive out other competitors. TI Calculators is a classic business case for driving pricing to create volume which in turn drives mfr economies of scale.
