In addition what you already know about the Raritan Marine
Elegance, it's made in the US, is backed by readily available outstanding tech support and parts
(in the unlikely event any are needed) are available from just about any yard in the US. Plus it's been the top rated macerating electric
toilet since Raritan introduced it more than 10 years ago. And I'm not aware of a single
owner who's ever posted anything but a rave review of it.
As for price
...I have no idea what prices you've been quoted for it and the SaniMarin, but this retailer has it for about $750 INCLUDING the optional "Smart Flush" panel. Boatersland Marine Elegance
