this is something I have been looking into for a while.
see this thread
viewtopic.php?f=6&t=4344If you don't have a vacu flush now, it would be very pricey to upgrade (thousands, to swap out entire new system), if you want to upgrade to electric, can be done depending on exactly what you plan to change out, anywhere from $200-$600.
I think all I am going to upgrade is the electric base with macerator.
