yes aax is more expensive but definitely btr than zxts as it made of an alloy that are make most good qaulity cymbals while zxts are made of the b8 alloy only. istandbul should be cheaper than the higher end sabians... sorry 4 de confusion, but aax's are quite cheap among other sabian casts like hhx or hand hammered, hey but coldplay, softer music, maybe a good idea to get warmer cymbals like zildjian or bosphorus or paiste traditionals... axx is cutting, to match with heavy power chords or cool licks
