Cheap Polar CS600 w/Power - what's the catch?

I'm really happy about the power levelling - I have trouble keeping my power output up when I'm going downhill. How soon can I enlist?
I'm not so sure that gold is a good frame material, however, perhaps a little soft and heavy. Might still be cheaper than some plastic frames.
Perhaps you might like to explain the "wow" bit - I guess I'd say it too when I saw an unpainted gold frame.
