played HHX's at the store, for all that is worth. i thought they were more interesting sounding than the Ks.
great cymbals generally arent cheap. although, there are many cheaper cymbals that sound pretty good. wuhans for example, are pretty decent. their basic cymbals are more in the AA sabian and A Zildjian model, but are a bit more "trashy" in a cool way. less controlled, more harmonics. kinda what you would expect from a chinese cymbal trying to sound like a turkish one.
what is always suprising to me is finding a really great drum shop with lots of used cymbals and trying them all out (annoys the other customers, but what are you gonna do). generally, the more expensive, good rep ones sound better, but cymbals are not very consistant- so you can find cheap ones that sound pretty good as well.
