What to use for diaper pail?

[abbysparkles]

I've been trying to use the Diaper Champ for my cloth diapers but it's not working. I have a Planet Wise wet bag and it does not allow for the diaper pail to close. So, I need to buy something else but really want it to be inexpensive and effective. A friend recommended a diaper pail that just looks like a plastic trash can with a step lid. Couldn't I just buy a trash can and use it? If so, anyone have any recommendations?
Thanks so much!
