Never been a big fan of LEDs, sure, they don't emit much heat, but you won't get the rock hard buds a HID will produce and you won't get the same footprint/coverage. LED is a niche market thing.
That being said, I am selling a 400w air cooled hood with built in ballast and an inline fan to vent the setup, comes with ducting and a 400w MH Bulb. All for $200 :) Let me know if you are interested!
