New Toilet install/Basement
My friend was considering a Mascerating toilet for his basement bathroom. For a while. We researched them quite a bit and found lots of praise. We even found that a guy we know has one and loves it. Never had a problem. He was the one where the pump hides behind the wall too. The one big drawback is that they are incredible expensive. Upwards of about $1000 for a nice setup.
BTW, funny ending to the story - I had never actually been in the basement of his house the whole time we had consider doing this. When I finally went in I learned something interesting. The sewer pipe was just below the surface where he wanted the toilet, not above it. $150 later and a little bit a work, we had a regular toilet in place.
