I have an extra but it does not have a faucet connection on it. You would have to put what you want on it, probably easy enough with a visit to Home Depot. If you're interested, PM me and we can talk price.
Same as r-brian here. I have an extra, but the hose is rotted off. If for some reason his does not work for you, and you feel like fixing mine, drop me a line.
You could try E-Bay and probably find one super cheaply.
