I just moved over to cree LED's. If you have enough "electrical" ability and knowledge I strongly recommend buying a DIY kit and building your own strands. I just replaced my PC's with 12 Cree xp-g LEDS ( I plan on buying another 12 soon). Needless to say, I am now a HUGE LED fan. The colors, brightness and ripple effect are 100% better than my PC lights. I was keeping a clam with my PC's(bad I know) and now, just after a week, my clam is twice as pretty and much "happier" looking with the Cree LED's. Also, if you DIY, cost can be significantly cheaper with LED's. Through Rapid LED, it's around $100 per 12 LED kit.
