Pioneer A05. It isn't dual media capable like the A06, but it's a great drive. For around 230$, you can get the A06 at Newegg. It's been rated the current #1 by PCWorld and Maximum PC.
Pioneer DVR-A05 for single-media (-R/RW) burning with extremely high compatibility. DVR-A06 for multi-media burning, with compatibility that has to be just as high.

Get a drive that supports +RW and -RW
A drive made by a reputable company would be the best idea; Stick to Plextor, TDK, Sony, Pioneer, LiteOn, Toshiba, Samsung, etc.
