I pretty much agree with everyone else. It's not particularly easy to keep a certain cymbal line sounding the same for 40 years. And, I would argue that cymbals are the most critical piece of percussion in the kit, when it comes to consistency.
We buy certain brands with certain sizes and tempers to make sure we get the sound we want, and more importantly, be able to go back to the store 1 year, 3 years, 10 years later and get the same cymbal to replace a broken/wore out one, confident that it will fit right in like nothing happened.
So, any company that makes their own product or even re-labels another is a legit company, for all intensive purposes. However, the past is still the best indicator of the future and a company that has little past or a murky one, will take a long time of consistency to become 'legit' as a viable alternative to names like
Meinl,
Paiste,
Sabian and
Zildjian.
For auxillary cymbals, i.e. trashes and chinas, the market might be more lenient. I dunno. And some people like to mix up their sound every few years. But, I have always been quite brand-loyal when it comes to something I'm going to drop considerable money on.
