I'm getting speakers for Christmas. I don't have time to order something online now, so it's go to be whatever is in stock in the stores around town. So my choices are: JBL Creatures Logitech Z640 5.1 Logitech Z-3 Any recommendations? I've heard the JBL's. They sound good. They weren't as loud as I would have liked, but I couldn't find the volume control on the speakers so maybe that's why. The Z640's are half the price of JBL's, so I doubt they could be better. I don't know anything about the Z-3's. Please help me!
