for years, since i got my 52x plextor premium, i've been a plextor guy
their drives always had the best features, incredibly accuracy, awesome speed, all at the complete expense of quietness, they just SCREAMED like a jumbo jet. AWESOME!
but i just recently got burned (no pun intended) by a plextor 16x dvd-r (in fact 3 of them, that all died) and now i've been using a lite-on 16x dvd-r drive that i got from walmart for $49.99, and doesn't have as many cool features like my old plextors did, but the thing is deadly fast, and has yet to produce a coaster.
And next to the plextor, this thing is SILENT. it's as sure footed, well made, and consistant as they come, regardless of price.
It will do cd-r, dvd+/r/rw, and dual layer discs at up to 6x, i believe.
no dvd-ram support, but i don't know anyone who uses it anyways.
