I was thinking of getting this a while back but didn't go through with it cos I think its a little too much to pay for lights. However, I don't think the 150w MH version cost so much though. If you can fork out the dough to pay for it, go ahead. I'm sure you can trust their quality.
You should also check out Aqua Connect lights. I'm using the 250w version myself and I think they are fabulous and reasonably priced. You can get AT or Bio Ocean for a quote.
