I use Transcend cards myself, though most brands seem to be pretty reliable these days.
I own two of these:

One in my Caanoo and one in my Canon SX130. As CKeichel said, a card reader is highly recommended when transferring files. The Caanoo's interface is extremely slow and IMO is only suitable for quick changes to configuration files or copying small files over.
