Best diaper pail for not making your nursery smell like a port-a-potty?

We have the Diaper Genie and it's... okay? But honestly our room still smells weird by week 1. Someone recommended the Munchkin Step, someone else swears by just throwing them in a regular trash can outside the room. What's everyone actually using? Is the $80+ really worth it or should we just be more aggressive with taking trash out?
