So what's the big improvement:
1. The packaging looks great
2. The build quality is much better
3. It comes with a card reader.
From what I can see, those are the only improvements to the new (version 2) SCDS 1.
To sum it up, the new revised SCDS 1 was just a repackaged and cosmetically improved old SCDS 1. I can't recommend this card to anybody anymore, the EZ- flash V and the R4\M3 DS are just better slot 1 solutions.
