People have brought this up before me, but fundamentally price checks on anything nonstandard is of very very middling usefulness. Especially in current economy.
A BDS and Cele compass might have fixed prices, maybe even a 20/20 staff. Anything other than that goes by two things, and two things alone:
(1) what buyer will pay
(2) what seller will accept
There is nothing else to it. A price check is an estimation of what you think a potential buyer will pay, and what you think a potential seller will accept. This is going to vary based on your own likes and wants. It is going to vary by what is popular and what isn't. It is going to vary by demand and supply. But fundamentally all PCing does is propose a number for what I listed.
When there is a very niche item, sometimes the answer is not "I don't know" sometimes the answer is "I know it's worth something, by no one can tel you what, so jus wait and See."
And sometimes, what a seller wants doesn't comport with what market of buyers will pay. This doesn't even have to be the case for Q8 crystas; just look at Ikkis 20/20 Death offhand. Imo that's worth way more than 750e. The fact that it has no takers says buyers think otherwise.
The end all be all of this is that PCing is a horribly inexact art, especially nowadays.
