I think this is a re-badged Plextor 708A. I'm not sure how TDK is about firmware updates but I think this is a good deal.
Staples is selling the drive for $159 plus tax, use this link to take off another $30 http://prefctr.ddc.dartmail.net/Staples ... 0171052983
In PA, after the $40 MIR it comes to $140 plus change. Any opinions or experience with TDK's products and support would be helpful.
