I doubt many shops would have that in stock. It's a pretty expensive item for most shops to carry and not just order for someone.
Not really something a customer would just walk in and buy, unless they were looking for it specifically.
If you dig the sound, the one you get will be really close, and like Paradiddle Pete said, you aren't going to go wrong with it really.
The only real bummer is not being able to feel it when you strike it.
I have a 22" Paiste Signature China, and it's thinner than the 22" Zildjian Swish I have, and feels totally different upside down, or with the flange upward than the Zildjian--as you would imagine anyway, but it does make me play it differently.
Thanks, I own the discontinued Paiste Traditionals 22" swish it's a rarity.
I'm thinking of getting a big china to have rivets added to it, so I'm also searching for one in person to hear first as well as getting opinions on its sound.
Yeah I know... drilling holes in a new $500.00 cymbal.
