There's still a bunch of them floating around to buy. Although, the bargains are about gone on them. I got a couple (one numbered) earlier in the year at very low prices.
Another that just now seems to be getting scarce (in PE anyway) is the beautiful Ocelot. I decided to pick one up in PE this past week and had a rather hard time finding it. (already have a # combo that was cheap off the bay) After a few false orders (out of stock, after taking my order) I finally picked one up from a sporting goods dealer and it was their last.
A sprint run that has stayed around much longer than I thought it would, is the F/G Paramilitary. Those are still available at nice prices. Surely they will start to dry up fairly soon.
