Mini crib?

We are living with my parents temporarily and don't have a lot of space. My baby has been sleeping in his Rock n Play (he has terrible acid reflux so the incline helps) but he's getting too long for it so we want to buy a crib. We don't have room for a regular full sized crib right now so I'm looking into a mini crib. Does anyone have one that they can suggest? It doesn't need to fold or convert into a bed, I just want it to be small and safe.
