O2 Sensor

Well I had my buddy run diagnostics on my Blazer with his reader.(hes in Auto-Technology for college) All my O2 but one are junk, and the one that works is only halfway good. I have found 3 so far. Behind the Cat, before it, and a ways before that all easiely accesable from underneath it. Where is the fourth one on the Manifold I cant seem to locate it. I forgot if he said if I had 4 or 5, so help there would be appreciated. Also how much do they cost a peice?

I looked around but couldn't figure out what engine you have on your blazer. Is it an S10 blazer? 4.3Liter? I've got a 94 S10 with the 4.3L V6. My son has it now but when he gets home, I'll get under it and see if I can find all the 02 sensors.
