Having big blu Ray needs and 50GB being too expensive, I started buying Verbatim in the line of my Dvd habits. I then came to Sony for 1 year and tried Tdk far, everything works perfectly. It's probably not the best on the market but it is probably the best quality / price ratio. The BR TDK 25GB cost me less than the VERBATIM DVD DL. A check on the duration, as for others.
