Some used professional cymbals from ebay. Develop your ears early.
Paiste Signature, Dark Energy, 2002, Giant beat, et al are made from a B8 alloy, and they sound great! It's just that Zildjian and Sabian made the name of B8 mud in most drummer's ears.
DO NOT GET B8's you will shoot the drummer after three songs! They are way too bright and harsh for a Church, You'll slap your Mama they sound so bad! Go with the XS20's.. they really sound good. Ive bought them and used them in the studio, that's how nice they sound....The difference between the XS20's.. and the regular high end is; The XS20's.. are a cast sheet but is still made from B-20 Bronze, the same as all the highend AA and AAX cymbals....Most high end cymbals are B-20 and up. So think of the sound you will get from a B-8. B-8 is not some code name for the cymbals its the Bronze used in the cymbals.
