Has anyone tried those automatic litter boxes?

I want to buy one eventually, but I'm so unsure about it because there are so many mixed reviews. What brands have you used and did you like/not like it? Why?

I just plan on having a baby in the next year or so and I know my hubby will clean the litter, but I don't know. Something easier would be nice.

There is already a thread about self-cleaning automatic flush litter box.
