I had one with the bassinet feature and the changer, and never used the changer, but did use the bassinet feature.
I just saw one today for the first time that has a cosleeper attachment, which I wish was available when I had DS. I wanted to use my pnp as a bassinet, but it still required me to get up out of bed to look down at him and having had a c-section it wasn't easy. The cosleeper option looks great.
