It's a damn shame that the creator of this software has shaken the SD followers as he has. I am a Centrafuse user and just downloaded and installed the SD2 trial. It is much snappier than CF can even hope to be.
The interface needs work but changing graphics and such around is cake once the foundation is laid down. While I would use SD2 over CF there is no way in hell I am laying out money for a dev who turns out to be a total flake.
