Full Belts discussion

I realize this might be a bit of a stretch, but are there any reasonably good belts available for roughly $300-400? I’ve been testing out ball trap devices and my relationship with my wife has improved more than ever. However, I keep running into issues with the ball traps—sometimes it’s numbness in the legs, pain in the balls, or they pull out. My next thought was to go for a full belt, but those tend to be quite expensive.
