Looking to get 95 Teg

I'm currently looking at a 95 Integra GS-R that was stripped at a dealership. It apparently has some damage to the front and rear bumper/fender area's, no stereo, shiftknob, and other minor interior problems. My major question on this is concerning the ECU, it's missing and I need to know where I can get a new or used one and what it would cost me. The car only has about 75k on it and seems to be in descent condition otherwise. Any input as to what to look for or anything would be appreciated.

Thanks:alien2:
