I have no idea how much a "geezal" is, but installed price (they have to
install it or your warranty is void) of a VacuFlush is upwards of $2000.
Just the toilet--IF you can find anyone who'll sell it out the door,
'cuz they're only sold by "authorized VacuFlush Service

Centers," and
SeaLand will cut 'em loose if they catch 'em doing that--is about $1100.

A geezal is 10 C-notes. :-)

Seems about right. One of the local vendors had a "boat show special" on
VacuFlush at $12-1300......but I didn't inquire whether there was any
installation at all included at that price.
