The problem is that with the Maxell/Phillips you never know who is making them. Keep in mind that most name brands outsource to other manufacturers. Verbatim on the other hand produces all of their own D/L media made by their home plant(s) in Singapore (they do outsource their single layer media but use strict quality control standards on them). The point is that when you outsource they often outsource to several different manufacturers with varying quality standards. So one pack you purchase that is made by one manufacturer might be better than another. The other thing is that they can change out manufacturers at the drop of the hat, so even if you get lucky and get a line that is decent quality you might purchase several more packs just to get a different (or several different) new manufacturers. It's all about who is willing to give them the best price at the time. With the other brand labels I have given up on keeping track on who is making them for this very reason. So you can go with the best most universally compatible double layer media or try and skimp and save some money and play russian roulette with the other labels. I prefer to play it safe. As expensive as the media appears to be, you need to ask yourself is what you are backing up/burning worth more than the Verbatim?
Last I checked SVP shipped all over Europe. Not sure on the conversion rate but have a look at these and see if it saves you any:
EDIT I just checked xe the currency site and apparently it's 9.67 Euros for the 10 pack and just over 27 Euros for the 25 pack. Obviously that doesn't include tax or shipping but it might be worth looking into.
