Anyone own or at least try these powerheads?

OK, so a quick search for "powerheads" on the Evil Bay yields a large number of pumps that look an awful lot like Koralias. I've even been told (by the people that sell them of course) that they're manufactured by the same company that makes Koralias. For the price, I'm sort of tempted to buy a couple and test them out.......but has anyone else seen these? I seem to remember seeing these on someone else's tank, but I'm not sure.
ANyone want to chime in? Have them? Tried them? Thanks for the help!!

I guess you cn try at your own risk but I personally would just spend the money on the real thing. I believe the auction site is a great place to get some deals but on some things you get what you pay for. A buddy of mine bought a knockoff compact metal halide unit and had to replace the ballasts after about 4 months. The unit also wasn’t UL certified. I also bought a no name ballast unit that crapped out on me after about 6 months. I also have purchased several times so no name metal halid and compact bulbs and was really disappointed. So for now on, I am buying the real stuff. Just my 2 cents.
