Well... Pioneer have made good DVD burners for quite some time.
I use an older Pioneer (3 years old or so) burner with max speed 4x.
It still works just fine. And I can use any +r or -r (or rw) media on it
(at least I havn't found one that doesn't work!)

I guess I'll try to find a Pioneer burner for my next computer too
