RE: cuddeback
Here's my specific experience with the 06 vs. the 05.
Battery life on the 05 is better because the flash isn't so bright.
Flash is brighter (advantage for picture taking most of the time) on the 06
Battery holder SUCKS on the 06.
Weather proofing SUCKS on the 06.
My 06 would not stay on no matter how I put the batteries in. Therefore I had to reset date / time all the time and miss pictures.
05 definitely has shutter speed issues during the day. A fast moving target is blurry on the 05. Not so on the 06.
06 comes with NO accessories. I liked the cable with the 05.
