Ebay still brings nice surprises for items like 144 BCD chainrings.
I recently aquired an NOS 144BCD Mavic SSC 53T chairing (the one with the dark anodizing which is more expensive and harder to find than the silver version) from a seller at eBay for much less (40 some bucks, I suspect that it would be usually be at least double that) that it would usually cost because the seller made a mistake on his description/title for the item saying that it was a 130BCD ring for a "Starfish" style crank. The auction pics caught my eye instantly, and I looked at them closer and was sure it was a 144BCD ring.

The "Starfish" crank fans did not bother bidding for it as they don't like the dark anodizing that was never standard for their cranks

, while the owners of the older style 144 BCD Mavic SSC cranks did not bother to bid either as they see the "130 BCD" title on the auction

.
Blam, I bid for it during the last hour of the auction to stay under the radar and I got it!! Now My dark colored SSC dust caps and chainring bolts have proper chainring company on my 144 BCD Mavic crankset!

Sooo.....If you wait patiently...they will come!
