 removed. It's pretty pricey at $500, and its yield of 2 pints per hour
 sounds about equal to the perspiration that would be needed generate the
 800lb/sq inch force needed  to force intake water through the membrane.
 
 Anyone have experience with such a unit?

Rich,

I don't have any experience with water makers, but I did do some research on 
them for a trip I am planning.  My conclusion was that the water maker you 
mentioned was too slow to use for anything but survival purposes, which is 
how it is marketed.  Paddlewise's Cajun Gulf of Mexico crosser, Arthur Hebert 
 <A HREF="http://homepages.gs.net/seacajun">Arthur Hebert's Sea Kayak Page</A>
, sent me an email in the past saying that the higher capacity manual water 
maker he used on the crossing felt too slow and that if he had to do it 
again, he would get an even higher capacity model.  Do a search for the Pur 
website, and you can see these higher capacity models, which I think ran in 
the $1000-2000 or even more range.
