A question for Peggy Hall but anyone is welcome to jump in...

If money were no object, and there was sufficient space, water & power, what
head would you install? If seen comments that Vacuflush are great for people
with more money than sense but have not seen suggested alternatives. Is a
Vacuflush the best there is? We've pulled the failing toilet out of our 32-foot
powerboat and quickly need to make a decision on having a new one installed.
Thanks.
