What I think is going to happen is we will see less and less quality "good finds" in the local antique shops and more and more ebay sketchy deals.
Sadly, what sucks is that a lot of good razor or potentially great restores are ending up in the hands of those just starting out.
This problem is what has happened in my other hobby reefkeeping, basically what happened early on was newbie's grabbing very difficult specimens or mixing the wrong fish together practicing bad husbandry because they saw the movie Nemo. Eventually these fish would die in their care from lack of experience or knowledge and vendors trying to make a buck sell without morals.
Not all vendors are this bad some actually want to see proper husbandry occur. This can be kind of what maybe be happening here, lots of good razors going too quickly to those not invested in this hobby.
The only thing that saved reefkeeping was coral propagation(farming) maybe there will be something to keep the prices affordable in this hobby too.
