Well I think the TK is a suit you truely make your own. My first suit was a hand me down used FX and I thought getting everything together all at once put me at an advantage. WRONG. I ended up having to resize the thighs and change out this and that to even get it close to basic level approvable. I've also seen people that purchased AP and another armor maker that requested it ready to wear and in the end they did a ton of work to get it fitted correctly for them. I'm on my 2nd TK now which is AP (I need to update my banner I know) and I started on it from scratch. That one truly came together as I hoped it would and now I'm very proud to take it out on adventures. I'm not saying it's impossible to get a suit out of the box that's 95% of the way there for you, but don't be afraid to take time with it and by all means check with other local TK's that can give you valuable insight and advice on your build. With the new movies and so much going on with Disney and Star Wars, it's a great time to be getting on board.
Now that I am thinking about it, I'm going to go try to update my banner....
