Not sure if your aware but tunze will be releasing some new controllers soon (Early 2005 avaialble in Australia). These controllers look and have some very sexy features.
The new controller seems worthwhile with the fact that you can hook up to it or it may come included, not sure, a small white led
light (moon light) which you can set to your current lunar patterns.
Just bought the turbelle and was informed by my lfs
, thought it was interesting. Pricewise i would assume it would fetch more than their current A$100 controller.
