Affordable CB6000S?

Hello!:hi: My girlfriend prefers that I keep my CB6000 on most of the time. It only comes off once a week during sex and again when I go to the gym for workouts. I’m happy with how things are, but there is one issue. After wearing it for two or three days, I get quite aroused, sometimes enough to ejaculate inside my CB. It isn’t very pleasant, but at least something happens. 8) The “game-room” in my CB6000 feels a bit too spacious, so I am considering purchasing a CB6000S. I currently use the medium ring along with the smallest spacer. Does anyone know where to find an affordable CB6000S? -Just the cage.
