I am thinking about upgrading my machine, and might put an internal CD burner in, because of the fact this USB one I have now is only 4x and doesn't work in linux anyways. Which models work best, do the A-Open, HP 93x series, or Plextor burners work? Another benefit to the internal burners is that seeing I use both linux and windows, I could use Ghost with rewritable CD's (my current internal drive won't read them).
