Geez
I thought I went a bit extreme when I panicked at the prospect of getting a Sanyo...but I had already posted info and links to cdrinfo.com's review of the Sanyo 12x10x32x...YES it has burnproof, YES it has a 2 MB buffer. In fact, it is very nearly as good as the Plextor EXCEPT it is missing DAO RAW...now, how important this is depends if you specifically need this feature. If you don't know what this feature is, you probably don't need it anyways. BUT, it does lack this, so the sanyo is a bit inferior to the plextor.
Shipped 2/6...still waiting...(live in ohio, so maybe it's got a long way to go)
