After 17 years using a bucket (with sawdust) and a portapotti, we finally got ourselves a Separett toilet. It is absolutely brilliant. Unlike your ordinary flush toilet, there is no smell at all, even it has just been used. There is also no drain on our rather fragile water supply. It is neat and easy to empty and clean. We still collect the urine to use for composting wood shavings for mulch, but it could just as easily pipe away into the grey water system.  An added bonus is that an old friend who has refused to visit because of our toilet system, now has decided (after seeing photos and having a description) that she will probably visit next summer! Full marks on a superb product.
