Unfortunately this model does not seem to be available online any more from FastMac.com; I don't know whether this is a website glitch or whether the low-end model has been discontinued, so I'd suggest phoning if you are interested. The least expensive model FastMac.com currently offers is a slimline BD-R 2X for $260: http://store.fastmac.com/index.php?cPath=10_2_52
I use my Digistor Blu-ray drive for both my Win 7 and Macbook Pro. Its got a lithium battery built-in to help power the drive, so just one usb cable is all thats needed. This comes in handy when I have to grab files from here and there or do a short burn.
