Hello, new here and we are putting together some interactive projects for a museum we are opening. I am hoping to purchase a color video scope, and a Rhythm Scope. I am able to do PayPal goods and services and am really hoping to get nice working units. I missed them before they retired. I have built my own interactive exhibit with a Xbox 360 Kinect and pi 4. But I need the rhythm scope for my son and his drum setup, and the video scope for my exhibits.
