Have you checked with qtan on e-bay. If he doesn't have any in stock - e-mail him. Your other option might be once the group on here receives the incoming shipment from the iMav group buy. Someone in that group might be willing to sell theirs.
I bought two from qtan on e-bay due to breaking my first one. The Poker with Reds is a nice keyboard. Great for traveling, light weight and gotta love the reds! They are definitely a switch type that comes out in in limited editions and then is hard to find. I bought two of the Filcos, one full sized and one TKL and they are both out of stock everywhere as well. I just recently sold my full sized Filco with reds and had no problem selling it. I guess when some of these groups say "limited" they actually do mean it.
Good luck with your search.
