Make sure you listen to them in person before buying them.
Seconded. If you like the sound they give, they're great value. If you don't like it, look for something else. Wuhans are a love-em-or-hate-em brand of cymbals - they're definitely good stuff, but they don't appeal equally to everyone.
Also note that Wuhan S is the, umm, "regular" line - hi-hats and crashes, not chinas. Wuhan chinas are very trashy, but not so for the Wuhan S. What I've heard about the Wuhan S is that it's very bright. It puts some people off, but others love it.
