I bought one...here's my review:
The Plextor PX-716a is a very beautiful drive. Included in the package was a black faceplate and a piece of 16x media, two things many manufacturers neglect to include. A DL disc was not included. Installation went without a hitch and Windows detected the drive right away. Nero detected the drive also. However, the drive wouldn't detect anything! No matter what I put in it: DVD, CD, burnt, pressed, blank, anything. Took it out and returned it to Best Buy and picked up a Pioneer A08XL. Patched it to >NIL:'s hacked firmware and am now burning 4x media at whatever speed I want.
Pros:
None
Cons:
It simply did not work.
Now if the Cons do not bother you I would say to buy one. But hey, it's your money.
