if you want to burn music, the yamaha light-speed is your drive
if impeccable quality for movies is your cup of tea, plexwriter
if a damned good burner that wont roast your wallet is for you, take the lite-on...sony's are ok but the buffer is crap so u coaster a good bit
I have a Samsung SW-216B (16x10x32) with the "Designed for Windows XP" logo. Haven't got a coaster ever!
It has the technology to prevent buffer underruns, and the firmware can be upgraded online. Got it for a really good price too.
I've also heard good stuff about Plextor and Yamaha.
I was lucky enough to get my mits on the Mitsumi TE4809 48/24/12 CD writer, which for a limited time was shipped with a 16mb cache. Since then I've only had 1 coaster, and that was because I was tryin to do about 10 things at once.
Mitsumi/Lite-On are two of the better manufacturers around at the moment.
