I have a NEC7700a (revision 1.03 after firmware update) no problems apart it started running slow when i installed XP (untill i upgraded the firmware) and now it runs a treat 3mins on a 12x burner, im not sure how long its supposed to take, but that is more than acceptable for me anyhow, i've fitted quite a few liton drives and have had no problems nor complaints, about the drives, well actually i have but it was down to user stupidity.... IE, burning a CD and thinking they could reuse it later... (CDR and not CDRW).... dumba$$es
