Rgr all.
Most of the time, when someone does that they go to the dark side and start charging other community members 2000x the cost of the part. Because <insert reason about supply, demand, cost of renting a warehouse or junk yard, blah, blah, blah>.
I tend to favor the $50 civilian solutions part that can be found by anyone online over the $600 scalper parts (that cost $50 at auction). But anytime I can make something, I do so as well. And I share the diy with anyone who will listen.
So good on ya...
