low-cost workstations

[Ranjan Bagchi]

I am realizing that within the next year I will be in the market for a low-cost
workstation running unix.  By low-cost, I mean $5,000-$10,000.  Essentially, 
what am I looking at?  I'd like something with a math co-processor, and
some form of graphic interface.
 
In addition, where do I go to purchase these things?  Yellow Pages?
