By most reports on rcu, it was not worth the ridiculously long wait. Almost everyone has said they tossed th supplied hardware because it was junk. The scheme they signed up for was not the one they got, either. Many have stated that they should have just gone with the aeroworks.
Now, the aeroworks does tend to tip the scales in the 23 pound range, and Dietrich states around a 20 pound finished weight. If their claims hold true then they may have an advantage there. Then again, its pretty easy to get the aeroworks to around 21.5 pounds with a little carbon fiber - I got mine down to 20.9 pounds with a cannister.
