You know, it is not even close to being too late for PRS to do something like this.
"Due to unprecendented demand, PRS is expanding the run of Nebulas to allow ordering an unlimited quantity through 1 March 2020. Anyone who ordered one just because it was limited to 500 (and not because it was a great finish that happened to be limited in quantity) was foolhardy, and should immediately renegotiate with their dealer for a more mature purchase. Anyone who is already selling them on Reverb or eBay for ridiculous markups - well, go suck eggs."
The Anderton's guys even said "you could have added a 'naught' [zero] to the quantity" - i..e the run could have been limited to 5000, not 500.
Or offer a second run of 1000 in maple necks.
@Shawn@PRS ? Maybe drop a hint to the marketing/sales folks?
