I had an old 4x2x8x (I think it was 8x on the read CD) Que! USB drive that I sold on eBay. I never used it with iTunes (I sold it before iTunes came out), but I did use it with Toast and I made far more coasters than CDs. The USB interface was slow and unreliable and caused Toast to hang frequently (I ran it on a B&W G3 300 MHz with 128 MB at the time). I just got my new Que! Fire 8x4x32x from Mac Mall today and burned a CD with iTunes on a PB G3 2000 400 MHz 190 MB and it worked beautifully. I did not even need to install any driver software. The PB recognized it immediately, as did iTunes. It is a lot bigger than I would have liked, but for $220, I couldn't pass it up!
