I am not really sure why the Caz series is so cheap. I have tried Caz, Rockbeat, F5, Raw series, and the Caz seems to be the best for me.
The crash - i liked it so much I ordered a 20" Caz crash, which I also fell in love with instantly.
Caz crashes are thin (not paper thin). The response is really fast and it opens up really easily - you dont need to hit it hard to get the full sound the crash can offer - you can listen how it sounds on my bands youtube channel (search "amendedband on YT). Most people say its for jazz, pop or rock. I play progressive/death metal with Caz crashes and cant find a problem with that - thin crashes are GREAT for recording for any genre.
The crashes are dark and fast - the way i like it.
As for quality - my 17" was a bit dirty - I found several oily black fingerprints on it. The 20" crash was just absolutely perfect.
A note for Zultan crashes as a whole - i ordered my 17" Caz along with a 18" Rockbeat crash (which CRACKED - I will write a review on this crash after my replacement arrives), and the crashes sound almost the same, which was a bummer (you can even hear it in the sound samples). The Caz however is slightly better sounding for my taste.
All in all - I highly recommend this (and any other Caz series) crash - you will not get anything better for your money.
