They seem pretty nice for what they are - i took some liberties (see my reply to awesomepants )
The goggles have nothing to do with the type of Tx/Rx you use but here is what i am using
600mw Tx/Rx combo since i have a go pro already.
The camera, video tx/rx, and goggles/lcd screen will put you over budget before you even get to the quadcopter build.
Here is the build list I have just ordered this morning for my own FPV:
"Goggles" $60
Video TX/RX $48
Camera $70. You could go with a cheaper one than this.
