Looking at the website, the A41 kit does include a controller. I asked for quote earlier this year while I was waiting for my TKX to ship and it was about $4,500 for everything. That's considerably less than I paid for my TKX kit and it probably would have been a simpler install since I would not have to add a pedal or go through that whole bellhousing alignment debacle.
Note to self: do your research BEFORE you spend your money! I have no regrets. Ultimately, I'll probably be happier with the TKX, but I might have taken the A41 route if I had know about that option.
