I don't need a dual format burner.
Unlike DVD-R discs, there are only a handful manufacturers currently producing DVD+R discs. As long as you stick to name brands of +R discs, I doubt that you are going to have coasters with this model. Just remember that Lite-On is probably going to cut the price for this model when they introduce their dual format burner next month, and 180€ is not a bargain for a single format burner. Check out the NEC ND-1100A if you don't need the DVD+RW 4X write speed.
One unique feature of this LDW-401S is that it's able to burn Ritek made 2.4X DVD+R discs (media code RICOHJPNR00) at 4X, not sure if the burned discs will last long, though.
