Looking For New Burner

Well my Pioneer 115 seems like sooner or later it is going to bite the dust. Sometimes the tray opens, some times it doesnt, and beyond that I want to upgrade to a SATA burner.

Burn speeds is probably the most important thing to me. Good reading abilities would be a nice but not so much required. Ability to patch to region free is a must.

I was going to go for Samsung SH-S203 or Pioneer 215 but it seems there long gone. The Lite-ON IHAS422-08 and the PLEXTOR SATA Model PX-806SA SW seem to be very popular but are they really the best?
