I wish I had one I loved, but I don't. I have a Royal Sovereign but it hasn't been too reliable. The humidistat doesn't work like it used to, so it keeps running. But I do like that it has a pump to pump the water up and into the utility sink, so I don't have to keep emptying it. At the time, this was the rare model that had this feature, but it's become more common now.
When this one totally dies, I'd probably get a similar model from a better company like this:

Good luck!
Edit: I would echo skullguise in that all dehumidifiers add heat to the room, since they don't vent out the hot air, like an air conditioner. This might be important for you, since it's a bedroom. Even our basement can get too warm in the summer, when it's running constantly.You might be better off with a mobile AC, which I have in my upstairs bedroom. We have this:

It works fine for a small room, but we got it because it's cheap. I'm sure there are better models.
