I've not seen too many of the Pong 10 models. I have a standard Super Pong that I bought for $3 at a thrift store with the box and instructions. I also managed to pick up a few Coleco Telstar pongs and an oddball 4-player one that looks like a prop from the original Star Trek. These were all part of my console collection.
I was always amused at the first feature listed on Super Pong's box: In color on color television sets!
