It does seem to be getting slightly better. I just looked at rpilocator.com, and it claims 12 different models are available from some retailers (none in the US, though). The models available are... not exactly desirable. But the last time I looked, and all prior times, for the past year or two, I would see at most one or two models available, and often just nothing.

So it's still useless, but... less useless than before? And maybe that means it'll get to a point where useful models are available again soonish?
