I've been using two of these power strips on my 70G reef tank for about 6 months and they are great. The second power strip plugs into the 7th outlet on the first power strip so that you only have one power cord to connect to you GFCI. It makes maintenace so much easier when you can simply switch off any individual pump or lamp rather than unplug it.
FYI, I have found an even better price, only $14.50 each, see the following link. The company is based in Arlington, TX

I'm in the process of setting up a 215G FOWLR and just placed an order for 3 but they are back orderd until 2/15. Well worth the wait though.
