Yeah, I've bought that drive, and it's great.
However, I doubt there'll ever be 32x DVD burning drives. 32x would mean 44000KB/s, and that, I think, is way beyond theoretical maximum of DVD discs.
Come to speak of it, I would be surprised if anything faster than 16x would come out. 16x for DVDs is like 52x for CDs. Won't get higher than that.
