This thread is for you.
I'd say the best writers for general purpose burning are the NEC 3500, Pioneer 108 and LG 4160.
If you are exclusively burning movies then the BENQ DW-1620 with a bunch of +R media is more appropriate because the drive has native bitsetting support. (For best compatibility, +R with bitsetting is the media and burning method of choice.)

As to good media, finding this stuff is a black art. If it is from Taiyo Yuden or Mitsubishi then it is good. If it says Made in Japan or Made in Singapore, it is good. If it says Made in Taiwan, well, life is a box of chocolates. There is tonnes of reading about this in the media forum.
And when asking about media, make sure you specify the country where you live, because the availability of good media changes from nation to nation.
