There’s a Catrike Trail on my local CL right now, asking $2000. It’s an older non folding model resembling only the Pocket in the current line up, with a mesh seat stretched over the frame. I’m not sure what makes it “trail” per se. Edit: it seems that the current Pocket has 3 BMX wheels like both the older and newer Trail, while the older Pocket had 16ers up front. A little confusing.

There’s a seller in Minden NV blowing out a whole garage full of recumbents including a coupled Rans tandem. Prices look optimistic. I’m not shopping for 2 wheels but I figure someone here might be.
