Never heard of them - As long as the card is reputable then it should be fine. iirc mine are mostly sandisk.Cool. I need to get one of those.
I'm looking at the Ducati range of CFs. They look awesome and I checked on dpreview.com and they showed that these cards allow remarkable copying speeds.
I'm using a bit of a convoluted process now that I use a GPS datalogger. I copy the GPS data track using windows (via parallels), copy all the photos from the card onto my hdd, append the exif, then import them into Aperture which then does its thing. Patience is a virtue
