Knee controller is fine, no problem getting used to it, I promise. You could alway get a pedal if you like to, but I kept the knee controller on a bent wood case machine when I had it rewired. I have used a 99, 201 and an Elna with knee controller. Some cabinets had a combinational electrical trealde setup and it was connected to the main pedal. A 115 is suppose to be faster and lighter running than a 201 with the same motor setup. I am so envious.
