Are you wanting to buy LEDs because they are cool?

The one thing that is certain in my mind is that LED technology is still in it's youth - they will get better and cheaper. If you are in no hurry, wait. Look at what $500 buys in a PC today vs. even five years ago. The same will be happening with lighting technology.
