I have a miox and a steri-pen. I like them both. The Steri-pen is faster and easier for water bottle volumes.
I've heard good things about the MSR filters.
I like the idea of the steri-pen. I would love to try one out. It does seem very easy and compact.
MSR has some nice stuff too. All the choices <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" />
