I would say the DVC100, or something with a lower number. The DVC100 is white. I recommend these over higher models for one reason: if you want to stream video on the internet, you can't use the others.
The recording file on the higher models is an .avi, and won't be recognised by streaming sites. The recording on lower models is an MPEG, and will be recognised. Sound will not be recognised on any model of Dazzle though.
