I have used this one for a few years now and have never had any problems with it. The "extra firm" bristles are really nice. And they are truly "extra firm". I have really thick hair so it's nice to have that, but if your hair is less thick you would probably do better with a softer bristle.

Also, a lot of health food stores carry Bass bath products so you can actually go and look at them before buying. I got mine at a local health food store here, but I've seen them at other more chain-y places like Trader Joes and Whole Foods.
