Here's a link to a place in Oregon that's selling the LED bulbs. Yes they're expensive, but so were DVD players just a few years ago.

I'm thinking about trying some of these as I've found through trial and error that the CF bulbs do not last long if inverted in a downward facing socket due to ballast overheating.

Keep looking for more sources and post them when you find them.
