Well I have some thoughts on the katadyn base camp since I was able to put one to use recently. Bottom line was that if you weren't in a hurry it was fine. I found it frustratingly slow when compared to the platypus clean stream which I also own and have used.

The clean stream performs quickly and efficiently but holds less than 1/2 the water the base camp does. In my mind this is the way to go with 2 or 3 trippers.

Once I lowered my expectation level and got about other business and would eventually glance over at 1.5 gallons of water ready to use I was a bit more satisfied. There are some other drawbacks however. Scooping up a couple of gallons of water and then clambering up a potentially slick bank after a long day might invite an unexpected spill (and I ain't talkin water). It might also take a bit more thought concerning where to hang 10lbs of water to initiate the process.

If I had it to do over again I would stay with the clean stream I guess and just fill a bit more often.
