Emperor 400

I've read that certain models are better than others. Is there really a difference and If so is the box that says pro series on top right the one I want?

I've always known an Emperor 400 to be an Emperor 400..never seen a "pro series" one. It's a good filter and one of the better power/hang-on-back filters. If this "pro series" is more expensive than the "regular" one, get the regular one. They've sold hundreds of thousands of them...haha
