1K static shift registers wanted (2533V, Am2833, MM5058, TMS3133)

I'd like to buy at least 7 pieces, and preferrably 30 or more, of any of the
old PMOS 1K static shift registers:

Signetics 2533V
AMD Am2533 or Am2833
National MM5058
TI TMS3133

There are probably other equivalents as well. DIP is preferred, but I
suppose I could deal with metal can parts.

Google turns up the usual parts brokers, but the brokers don't even
bother replying to requests for quotes.

I'd rather not have to design a daughter board to replace these parts,
though if I did I think a PIC in an MLF package, a surface mount voltage
regulator, and a few ceramic caps would do the job.
