Is there a "best of" link for externals?



I have been searching the forum for an external version of currently best voted drives which are the Samsung SH-S203B and the Pioneer DVR-112D:
Is there a section/link that has the “best of” externals?
Do the above drives have external versions?

I am looking for something that is standalone DVD player friendly. I will be using it ONLY for burning avi /iso files. Not looking for speed–8x is fine–and I dont need lightscribe.

Thanks in advance.
