Be glad you don't live up here in Canada, where these little critters are
costing me $32.46 EACH (Canadian dollars).

Not according to Siemens, the only manufacturer of blue LEDs that I know
of. Apparently, it is not possible to manufacture large slabs of silicon
carbide of the form necessary for making the LEDs. Unfortunately, I can't
find my Siemens opto-electronic manual at the moment, so I can't quote from
it. If anyone is interested, I'll dig it up and post the article.
