This is something I have seen in many kinds of expensive hobbies.
I get the impression that lots of people could not spend enough money on a (insert desirable thing to spend lots of money on) so they send it off *IMMEDIATELY* after receiving it to get it upgraded or fix a problem they once heard one guy might have had.
Cameras, Cars, Audio, Bikes, you name it.
It is kind of disgusting with vintage gear. At best it dries up repair parts for people who actually wear their shit out. At worst it just makes your own gear worthless, or your guru disappears with your gear.
PS: Totally guilty and hypocritical for what I did to my Melos. Just saying.
