good call on the cable length. There is one ebay listing for $6.58 with 1.8m cable. I don't think the extra cable is worth $3, just as I don't think the circuit board is worth an extra $10. I think these are still way overpriced. I think they will be more popular and widely used if the price comes down to $5 or less with the circuit board and 1.8m cable. The circuit board is not essential, but would make it easier to treat this just like a normal float switch, as the digital output will go high (or low, I can't remember which one) if water touches the sensor.
