The only ones I can get readily here in Ireland are Verbatim, and they are brutal as we say, i.e. from my experience they are of poor quality. I have bought a few boxes in the last while and each contained, on average, two faulty / dodgy ones. Could also be the way they were stored in the shop but I'm not impressed!

Good thing is that they have a lifetime warranty so I just wait until I have 10 faulty ones and bring them back to the shop for a repalcement box (or after 6 months mail them with the receipt to Verbatim).
