I wanted to see if there were any alternatives to the $100 superdrive that seems pretty fragile and some people suggested this Fastmac (http://fastmac.com/blurayext) for $110, which can ready Bluray discs. I did a little diging on this forum and found this tread (http://forums.macrumors.com/showthread.php?t=647170), which basically says it's a Panasonic (Matshita) UJ-120 drive in an external enclosure and an IDE-to-USB bridge. Then I went on eBay to see if they sell the UJ-120 and found this seller (http://cgi.ebay.com/Panasonic-Blu-r...rnal?hash=item230312ca88&_trksid=p3286.c0.m14) selling it for $80. I took the plunge and bought it, and it works fine. When I plugged it in, nothing happen, but when I inserted a DVD it played it and when I inserted a blank disk, it let me burn it with itunes. Anyway I just wanted to let everyone know that this is a great alternative for $80. I haven't tried the bluray yet, but I got what I wanted.
