Although the Pioneers are great burners, i personaly wouldnt get another one.
Ive had 2 which didnt last very long at all, the last being a 111D, i must have got about 30 burns out of it before it died.
Nec drives on the other hand that i use seem to last forever. Currently im using an Optiarc DVD RW AD-7170S, which is a new version of NEC drives, its also SATA and not IDE. It gets my thumbs up for sure, never had a bad burn and my 360 backups burned at 4x using ImgBurn work flawlessly.
Hope that helps
