does anybody have rough estimation of price for the piv system using double pulse Nd:Yag laser, image capturing device like kodak es1.0 and image grabber and so forth ?

About 100K. More if you need high speed camera and if you need 2 cameras for 3D stereoscopic PIV measurements.

you can save a little money if you decide not to get an off the shelf system and improvise some of the equipment yourself. I.e. use a non pulsed system with an optical switching device such as a Bragg or Pockle (spelling) cell. But in my experience if you have the cash then 100-120K depending on supplier and needs.
