I bought my cycloDS quite a while ago. I was looking through the reviews section just now and was suprised to see how many types of cards there were! When I bought mine, the cycloDS was the thing to buy, and it was an easy decision. If I had to do it again I really don't know where I would start for looking through all of these. I've been pretty happy with the cycloDS, but it's impressive to see how far this aspect of the DS has developed, and how quickly.
