I can't give too much input as of yet. I just got my 440w, I will prob get a second one as well. What I can say is the price isn't set in stone. There are some places you can talk them down and thats what I did. And when I wanted to know more information about the 440, I emailed the company. After talking to them a while, they wanted to sell me one, told them their price is pretty steep and I had a good offer from one of their vender companys. They ended up beating the price the other companies quoted me at.
It's def a very well built LED. Great packaging. And so far it has with stood so many smacks with my head. At this point I think my head will go before the LED heh.. I learned to look up finally..
Any ways, just saying you can get it a bit cheaper.
