I don't think they are in great demand. I bought one, with the appropriate books, for $20 at a local hamfest three years ago.
I'd always wanted a 990/189 since TI introduced it. It would have filled the empty spot of that KIM-1 that I wasn't able to afford in 1976. The 9900 series microprocessors had hardware multiply and divide instructions, which was rare back then.
