I was buying some SaniSolution refills for my CatGenie, and noticed the units are on sale until the end of the month. Perhaps someone will find this deal useful.
Personally I've found the machine to have its pros and cons. Automated cat waste disposal has been wonderful, but doing a thorough clean of the machine recently was a repulsive experience… As always, DYOR before buying something like this. :)
At this point it basically looks like a toilet!
