...after watching those videos (thanks Willowley!!!), this may not technically be 'centrifugal' at all - and if it's action doesn't degrade enzymes (and you don't want all the "options") - it might be worth the extra $100 smackers.
Hmmmm, if it yields HIGHER than the 8003/05/06, has a bigger feed with barely no "pushing", and doesn't degrade the enzymes - that'd be sweet, for sure.
