I plan on buying a dual-format DVD burner sometime this week and I was wondering if it is worth searching for a burner with an 8MB cache. Is cache size really vital in choosing a DVD burner? The only ones that I found so far with an 8MB cache come from either Plexor or Sony. (Any suggestions? I'm still searching.) I have a $200 budget and I want one with a black bezel. (I really don't care if it has either 4X or 8X DVD burning speed, just as long as it has 40X24X40X CD burning speeds.)
