Please post Soler and Palau links

I came across a thread on my phone over the weekend but when I looked for it on the computer, I couldn't find it. Can someone please post links on where to purchase?

Well, I found a link and I think it's one of the ones that was posted in that thread I was talking about.

My question(s) is.... in a 400 HPS cool tube cabinet, would it smarter to buy 2 separate 4" fans (one to cool 400hps and one for carbon/odor control) or should I stick with one strong 6" fan and do a cool tube/carbon scrubber combo?

If I do the combo, I will attach the fan to the outside of the box so that it sucks the heat out of the cool tube and then exhaust into the filter/scrubber.

and the link is here.
