For me, the TCA is a worthwhile membership. I received the latest issue of One Good Shot today see that their offering a 21" matte stainless OCTAGON Contender barrel in your choice of cartridge, cost $355. While this is about $25 more than what a factory bull barrel would cost, it's not an octagon. For me, it boils down to this, is it worth the additional $25 to have a 'unique' barrel, yes. I've availed myself to some of the past offers and intend to do so again. Additionally, I find that the articles, which are written by the actual members, to be very informative and interesting. I do wish though, that there was some definitive work out there in print which told the history of T/C and it's firearms.
