The `galaxy mall' site seems to have gone away and I can't find a sprayer in Camping World's catalog.
However, we just purchased two of the following sprayers; one for home which is working great, and one for the camper which I haven't hooked up yet. It is from www.HomeFocusCatalog.com, is model no. 146818, and is called `Double-jointed Swivel Faucet Head', at $9.99 each.
The double-jointed feature means that you can swivel it all around the sink plus it has two spray patterns; up for splash-free bubble stream, and down for wide-angle spray.
It's worth considering.
