The CBT is a great kit, but depending on how you finish it you'll over 2 grand, plus the amount of time it takes to put it all together. They're a great project, but not necessarily for someone who wants performance now. If you've got the time, definitely.
How many of the suggestions have you gone out and auditioned? Thats really the only way to come to any sort of definitive answer to your questions. Get out there and listen to some of these speakers and maybe you have. I just think if you had spent some time with these speakers we would have heard, yes I liked this and why, no I didn't like this.
Reviews and suggestions are only part of this whole process, subjective listening by you is what really matters. Specs and other people opinions will get you so far and help you weed out the garbage, but hearing is believing so to speak.
