I recently bough one of these and found that the rainbows were to much for me to handle. unfortunately I didn't notice this until after the time to return it had elapsed. It has under 20 hours on the bulb. It's about as new as you can get without still being sealed. I also haven't registered it so you should still be able to take advantage of the extended warranty. I'm asking $925 OBO for it plus shipping. I would consider trades for a portion of the price. If you live near Norman Oklahoma you can see it in action.
