Ha! B&H probably saw that those very nice lenses were going for as much as $255 on ebay and decided there was life in Pentax yet! I just got a pristine FA50 1.4 bundled with a clean ZX-5n on ebay for $300 and feel it was a good deal.
It might be true, though, that the FA primes will turn out to be Pentax's last great glass and at some point you just won't be able to get them anymore.
