Anyone have an air mattress that they like?

We don't have a guest room or pull out couch, but will be having my mom stay at our house for a few nights to watch the boys when I have this baby.

I know for a fact that she wouldn't want to sleep in my bed, and most likely, would tell me the couch is fine. But, I want something more comfortable for her.

I'm looking at amazon, and willing to spend around $100 -150 if it's quality (and has a built in pump), but the reviews are kind of all over the place, so I thought I'd check here.
