Since you are familiar with the controls on a motorcycle and seem to have a level of maturity, the busa would be a good choice as long as you respect it. It's comfortable for a sportbike and very docile when you want it to be. You will probably be okay as long as you take your time to get to know it and respect its power. If you are considering a used bike first, my suggestion would be the Suzuki TL1000R (last year made-2003). Though it is a race replica bike, it was very comfortable for me. It has the v-twin with lots of usable torque for the street. And welcome to the board.
