I have 4 DVD/CD-RW burners. One is built in to the laptop - can't specify a brand. The newest is the HP-740e w/Lightscribe, and I have two Plexies, the PX-716UF and PX708UF. All do their job as advertised - no problems. As you can see, I prefer externals - the only internal is in the laptop. There are several reasons for that, mostly stemming from growing up with burners for the last 14 years. I used to use all SCSI externals, but now have gone to Firewire, a SCSI derivative.
