Just bumped into another fan controller, looks pretty nice. The Lamptron FC5.http://www.youtube.com/watch?v=BY66Klwpofw
About the same price, Newegg has it. Does 4 fans though.
Edit: I canceled my order above on ebay, and ordered the Lamptron, as it supports 30w per channel apparently. That's enough to power a lot of fans on each controller, and it displays voltage if you prefer. I'm not going to be using the temp sensors, so this voltage readout is nice. It will allow me to quickly set the fans to a known voltage. Plus displaying a bunch of temps that aren't important could be annoying looking.
