I have a Plextor (8432A), and my friend has a Yamaha (dunno model, but its 8x scsi). His no longer works (burns all coasters, wont read a less than perfect disk) and mine is still going strong - no coasters when I leave my system alone (ide sucks), and will read cds that no other drive will read. Obviously, he could have gotten the one bad one out of a thousand, but this only reinforces my perception of Plextor as the best drive maker out there.
