But that's going to happen regardless of how many people are looking for the parts. Once the part is identified, stores are going to get inundated with requests for a "replacement part for my grandfather's doowhacky". That's just how this place is.
But it doesn't have to be that way. For example, say 1 or 2 of the parts ARE kinda rare. I'd personally rather see someone order 25 of them from a vendor that has them then have the vendor get 25 calls. By the 5th or 6th call said vendor is more likely to up the price, or become very suspicious. There is also a higher chance that one of the 25 RPF callers will spill the beans and let said vendor in on our little secret, and that could also jack up the price.
Right now, it just kinda seems like "let me make sure I get one for myself, then you jackals are on your own". And that's ok, too. Everyone does it.
Well, I can honestly say that is not my intent at all. I'd just like to see everyone here that wants to build one be able to do so for as little cost possible.
