oooh love this topic, I too have been considering purchasing the rotary Flex...wait I thought the Flex had both actions DA or Rotary? Maybe I'm confusing it
Well I'm sure it was the Flex that I was looking at and if I'm not mistaken it's the rotary, any who I've been doing some reading on it, talked to a few members that have it and use it on a regular basis and they have given me some beneficial points about it but some bad as well...just can't recall what the negative was but it was really good, I'll have to dig that e-mail up.
