Has anyone bought from LED Wholesalers ( http://www.ledwholesalers.com/store/index.php?act=viewProd&productId=524 ) ? I've seen a lot of reccomendations for prosourceworldwide ( http://www.prosourceworldwide.com/product_p/illuminator ufo.htm ), but there is a $100 difference in price between the two 90w UFOS! There are not many differences I can see, but maybe someone with more experience can look at these two options and let me know? Thanks!
