If you can find one, I would recommend a Samsung SH-S203 (SATA) or SH-S202 (PATA) drive. They are my favorite everyday drive - excellent CD & DVD writer & reader, and a useful DVD scanner. But they were replaced with the faster SH-S222/223 drives last year, but there are still some around (without resorting to Ebay). But make sure you don't get the newer SH-S222/223 or SH-S243 by mistake, they don't have a good reputation round here.:Z
Another good choice would be an Optiarc AD-7240S (SATA), or AD-7200A/S (A=PATA, S=SATA). There are also Lightscribe '1' & Labelflash '3' versions available. Again, don't get an AD-7220 by mistake (reported to be a rebadged Lite-On). I have an Optiarc AD-7200A and it is a good drive, but I prefer my Samsungs.
Both the Samsung and Optiarc drives have their merits, so you might like to read the CDFreaks/MyCE reviews & browse the forum to see what other people think before deciding.
Pioneer DVD writers are also popular and highly regarded (although I don't own one myself), but the jury is still out on their new DVR-x18 drives. The earlier models are difficult to find in the UK at the moment.
A lot of DVD writer 'faults' are actually due to poor quality discs. The MBI codes are Moser Baer (India), MKM A02 is a Mitsubishi Kagaku Media (Mitsubishi Chemicals) rewritable and the Ritek 004 is Ritek. Both Moser Baer & Ritek DVDs are of variable quality, especially under Memorex or supermarket brands (and others). I suggest treating yourself to a pack of Verbatim 16x AZO DVD+R discs (MCC004). It shouldn't matter if they are made in India or Taiwan, but I would play safe and avoid any made in China.
