We got a nappy bin - but it takes normally rubbish bags, instead of those really expensive cassettes.

I got it off ebay, just liked it because we needed a bin in the room, and its got thicker walls so the smell doesn't escape so much into the room. We used to have a Saftey First one that needed cassettes, but we also just used normal supermarket bags, cos i can't believe people would actually pay almost $20 for a cassette refill thing.

We only used the scented bags on really bad poos, i find no 1s don't need it at all. We empty the bin every 2-3 days, and just wipe it with disinfectant/cleaner then to stop the smells really building up.

Anyway, the bin we;ve got is great, not sure of the name, but i'll look it up. I got it off ebay cos they are supposed to be like $100 new, but ours was like $15 from ebay, which is the same price as a normal bin from kmart. I find this one slightly easier (although doesn't contain the smell quite as well as the safety 1st), then my first one because its deisgned not to use cassettes, with the other one it was a bit of hassle getting it into the bin part.
