Take a look a Zu pc's they do auctions on epay and you can get a new one at a good price.
I bought their BOK and it is not quite as good my Shunyata Diamondback but way better than some others that I have tried (none of which are on your list.)
If you are willing to go used I would recommend the Audience or Shunyata you cannot go wrong with either.
All my equipment is SS so I do not know how they might work with tubes.
