I have a Raritan Atlantes mascerating toilet. After I bought it, I was disconcerted to see a number of internet postings complaining about problems. So I looked at the Tecma and it had good specs but also internet complaints. I guess I was just concerted to think that if three people out of 10,000 have a problem, they'll post on the Internet about it.
The Atlantes is great. It's new, and I haven't worked it hard (living alone in the bus now) but it's efficient, reliable, quiet, and seems to conserve water. Can't speak to the Tecma, though. My memory is that the Atlantes had similar specs to the Tecma but a considerably lower price; you may wnat to check that out (but I'm hazy on that ...)
