An interesting question to ponder.
These are not made of B20 alloy-either stainless steel or brass. I know they have many holes drilled in them, so they obviously take some work to produce. They are priced like "real" cymbals. At least mid-to pro level cymbals.
Here's my question:
Do you think the prices are high because they take so much machining and labor to produce, or do you think it's because they are the "new, hot item" and drummers that need them (that live in apartments etc.) have no real alternatives, other than a competitors "low volume cymbals" which are the same price, give or take?
I guess they make sense for quiet practice, but have you played on them? It's like hitting a manhole cover! They play super stiff. I haven't played them for any prolonged periods of time, but I would imagine they would make your hands hurt after a while.
