Ok, came across someone at the university selling them for $40. Done a little research online, but have a question: I came across a lot of people saying that the iSub doesn't work on intel-macs. So my questions is, is the iSub different than the Soundsticks system (2 speakers and a subwoofer)? Also, does anyone know if this system will work on my macbook pro (Bought August 2008, runs leopard). As its usb-only, it's either going to work or not work. Thanks in advance!
