I stripped the parts from this: amazon.com/gp/product/B0095BXACK/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B0095BXACK&linkCode=as2&tag=krisk-20&linkId=ZEYLR7QXAFM7QAN6
so the total cost for the initial(FPV setup was only $20-$30 for me. The nano transmitter costs around $50 and camera for it should cost between $40-$60. However if you add the FPV setup the 250 mAh battery included above(it actually comes with 2) might be a little bit to small to give you any real flight time with the extra power consumption. So, finding a battery larger than 250 mAh and smaller than 350 mAh(just a guess at the cameras weight limits) would probably be another $10-$20. So if you are patient and spend enough time hunting down the lowest prices on these parts you could probably build the whole thing for around $110-$120 if you are lucky.
PS: if you buy the quad in the link above you have to rotate the flight board 45 degrees in the frame, which is a bit tough to do, but it won't flight without it. Also, you may have trouble connecting quad to controller: do this buy plugging battery into quad, turning remote on, then put the quad on a level surface(make sure the print is not warped or you will have to adjust so that the props are what are level), then push the the throttle up and down on the remote until it beeps and they are connected.
