Has anyone used AquaMira - a chemical water treatment? It purifies water with chlorine dioxide.
While I haven't tried the AquaMira product, it is a 2 part system, versus the Katadyn MP1 product:

Chlorine dioxide
can take up to 4 hours to remove cysts from water, but that is cold/turbid water. Otherwise it's the same 30 minute wait time as iodine (which will not kill cryptosporidium) and tastes a heck of a lot better.
