Brent, PUR makes one. Although I don't know any specific source, I
presume you can find it at SailNet.

I am departing offshore next April and I would like to include in my grab
bag a hand operated reverse osmosis water filter like the military use. I
have searched the net and can find heaps of places that sell electric or gas
powered ones, I can find articles about how good the hand operated ones are
but I can't find anyone who sells them.

Any suggestions would be appreciated.

Camping supply store?
