Micron Legends Scourge/Black Convoy - How Rare?

I've liked Scourge/Black Convoy/Nemesis Prime repaints ever since RiD's, and I've recently purchased an Alt Nemesis Prime from Savage_Prime (it's still on its way). I don't have G2 Laser Prime or Alt Prime, but I do collect Primes, so I've decided that I will buy Nemesis versions of OP's I think look better in the black color scheme.
Which brings me to Armada... I don't own a single figure in the line, because I just don't like more kid-oriented style and simple transformations/lack of articulation. One of the few that sort of interested me was the Deluxe Prime. Since I don't own him, I figured the Nemesis version would be pretty darn cool (looks cool in pics), but how rare is he? Do they ever go for decent prices (say, under $40 or $50)? I couldn't find any on eBay. I only want the Japanese version, because the US one has ugly tan-colored parts on it.
