Think I'd be more comfortable using a index-finger controlled one than a thumb one (but hey, I risk being wrong!), so thanks for the tips about the different models (: I'll try to hunt down some of the logitech ones locally, I'd need lots of buttons and preferrably a scroll-wheel so I guess my options are pretty limited (;

The Kensington looks good, but way out of my price-class. Thanks for the advice, I'll report back on how it goes in a while (;
