Using the benq 1620, I've found the dvd+rw from MAXELL and SONY to be quite excellent. Anywhere from 92-95% quality scores with no major spikes in PIFs. They are both using Japanese MID but both made in taiwan.
While not TY standards, very very good for +RW.
If you're feeling adventurous, you can try the memorez for about a dollar less, but uses the same jap mid.
