  Yup...Try http://www.gstek.com (dealt with them a lot, great vendor!) and
http://www.compsyscon.com.  These are relatively small outfits (compared to
places like Rave, I mean) and their stock changes frequently.  I like to check
their web pages every few days to keep up and see if anything neat has popped
up.

  Be very careful not to fall into PeeCee syndrome here.  The clock speed of
the processor is only a measure of relative system performance FOR IDENTICAL
PROCESSORS.  The HyperSPARC is a *very* different design from the SuperSPARC
and SuperSPARC-II used in the SMxx series.

  As a very rough example, I've found 100MHz HyperSPARC (w/1mb cache) to
be very slightly slower than an SM61 (at 60MHz).  I haven't benchmarked them,
but I've used them in performance-sensitive applications.
