Another thread has turned....
The original question about DP I think still has a simple solution. Use what you are comfortable with. The only thing that matters is the end result and your ears. All the rest are just tools. Sequoia is great I'm sure, however it will take me YEARS to be able to edit as fast and accurately as i do on pro tools. This is not because Pro tools is a superior editor. In fact i am sure it is not. I however have been using it for over a decade, and can move an manipulate it faster than anything else right now. It may not have all of the features of some of the other editors, but I know how to make it's features work. That is all you should be concerned with.
Also, I don't have to run pro tools on a God Awful PC box.
Find something in your price range that works for you and record and edit away. Remember that you are the the one making the recording, not the device!
All the best!
