Plextor is a great company, the support is number one as far as I am concerned. Thats why on part, why you have to pay a bit more for the drive.
Try finding a contact support page on Pioneer or Sony's webpages, or Liteon's. I am not saying there isn't one but it will take you all hours to find it and a weeks time to hear back from them, if you have a quick question and they call that support...
Plextor drives break just like anyone elses, IE it's made out of plastic. but it's the level of support makes this company number one. I had the button break on my older cd-r drive from plextor and I just emailed them and told them what happend and they asked for a mailing address no numbers or strange questions back, one week later I got my new face plate in the mail, all done over email that had taken place that day. was amazed at the level of support and service they give and offer.
what more do you want then that.
