If you're trying to do FPV on a budget then I think it would be very hard to go past this camera/transmitter combo I picked up from RCTimer for just over $26.
The camera is a CMOS variety but demonstrates pretty good resolution and acceptable light-handling characteristics. The 5.8GHz video transmitter performs well and even offers a 5V regulated power feed for the 5V camera.
All in all, I'm quite impressed with what you get for your money and although the camera lacks the CCD-based Sony 600TVL's wide dynamic range it is still quite impressive for the price.
Pro's:
- undeniable value for money
- 32 channel video transmitter
- easy channel-change
- built in 5V regulator
- lightweight (22 grams)
- wide voltage range 2S to 5S
Con's:
- CMOS camera susceptible to jello if vibes present
- no wide-dynamic range or other controls for camera
- camera has no mounting facilities (hot glue works though)
