Was just in the Downers Grove IL Frys this afternoon and they have OEM LG DVD burners on special for $12.99. Not sure if it is chain-wide or just the DG location. Sounds like a good time to stock up on spares.
They are also "M-DISC" compatible, which I had never heard of before today (had to look it up). Apparently this is a proprietary type of DVD media that can be burned only on newer LG DVD burners (supposedly readable on normal drives though). M-DISC is claimed to have a 1000-year archival storage life. Given that I'd never heard of it, and the lone listing for media on Newegg is a single disc for $5 I doubt I would ever make use of this feature.
