I have found the Panasonic (Matsuhisa) UJ-815 slot-loading Superdrive selling bare for $299. [URL=http://www.dfwdepot.com/uj815.htm]dfwdepot Superdrive[/URL] According to reports on the Firmware page, people have had a lot of success in installing this drive into Powerbooks with support for Toast, iDVD and iTunes disk burning. I can't guarantee that it will work in a Cube, although I suspect that it will and am considering putting my money where my mouth is. At $299, it may be worth it to further extend the life of my Cube. fwiw, dfwdepot is also selling the slot-loading Panasonic CW-8122 DVD-ROM/CD-R/CD-RW drive for $160.00, which (scanning through the Firmware webpage) is apparently the one used in the 12" Powerbooks.
