Most of the modern burners are comparable to one another in capabilities and build quality. There aren't any that have proved to be outstanding, and you'll find virtually no one around here who is enthused about the current selections.
The Blu-ray burners still seem to be well made, if you don't mind spending two to three times as much as you would for a DVD burner. There is an LG Blu-ray burner for $50, as shown in this thread: http://club.myce.com/f58/lg-wh14ns40-49-00-a-336844/#post2734259 That sale ends in three days.
But if you aren't interested in the more expensive Blu-ray drives, I'd say grab a Samsung, LG or Lite-on at Amazon or Newegg. Asus rebadges drives made by others, and the Pioneer DVD drives are not the same quality as they had in the past. Pioneer Blu-ray drives are among the best however.
