just want to chip in, a day late and a dollar short as always.
I have had great success with the saniflo toilets for reno projects. I have only ever had one customer come back with an issue, and it turns out he hadn't hooked the darned thing up correctly.
I just want to reiterate what mccmech said about keeping in mind how the saniflo has to be positioned. An old basement with a low ceiling is a terrible place to try to install one of these units.
In the last place I planned, the new bathroom backed onto a large closet, so we built a "shelf" at the back of the closet and hid macerating unit and everything else under it, with a door on the front of access. It is nice to hide all of the ugly working bits, if you can.
