They are not currently being produced so vendors with stock are asking big $$. Z1 or Coz may still have some.
I suppose it’s the vendors prerogative to mark up as they see fit. With limited alternatives on the market im sure there are people out there who will pay.
Coz isn't too worried about increasing prices when he can, he's also currently asking $2k for MSP manifolds now they're out of production
I’ve got a set of those new in box too looks kike they’re appreciating faster than my house lol With the keys I’ve been told it’s a case of inflating the price to discourage sales while stocks are low.
The problem with the keys is getting them cut. Titanium is very brittle and most locksmiths don't have the gear to deal with it. So - make sure you can get it cut before you commit.
Cutting a Ti key isn’t a problem -it’s a “key grade” titanium alloy and cut be cut by your run of the mill locksmith without any special equipment.
