Is this a reasonable price?

Hello fellow dinosaurians,

I have been looking everywhere for a copy of Greg Paul's _Preditory 
Dinosaurs of the World_.  I called a company in Denver, CO. that 
specializes in out of print books and they were able to locate two.  They 
are asking a whopping $72.00 plus $4.00 to $6.00 shipping.  I want this 
book, but WOW! 78 bones is a bunch.

Questions: Is this price reasonable?  Does anyone know where I might 
           locate it for less?

Thanks for any assistance.
