I personally these days mostly choose/recommend on a combination of cdrlabs, crlabs forum and cdfreaks forum and C't.(germanny)
Alot of people do check more than than just one source, me included.
But I always lean toward Plextor anyway.
I do ALOT of burning and they have never let me down yet.
By alot I mean that I have burned thousands of CDR's with my Plextor 24X and 40X CDRW's.
I went from a Pioneer AO5 to the PX716A and I will say it was an excellent buying choice as the 716A is excellent.
