Thanks Mike I will do my best to answer these questions.
1 Having been involved with the
Prochem, and only having limited knowledge of the others, I would have to say the
Vortex concept.
2 Dang trying to put me on the spot huh....two I think and only because of my experience and knowing folks who have them, Boxer 426 and Performer 405.
3 If he could find one, a unit based on the "original" Legend SE.
4 Having seen first hand the consequenses of H2O designs, I would have to opt for the Xen, and only because to make the H2O safe enough the would be too many safe guards built in.
5 I only know of one individual that uses more than 12 and he swears by it. I know more who use 12 and having seen first hand and talking with everyone, I would say, yes I am.
