I really wanted a Colecovision when I was 14 around 1983 but after spending so much on the Atari 2600 and games for a few years prior, my father wasn't going to spend the money on another console. I was so bummed because I spent a week at a lodge on vacation that summer and they had a CV in the main lodge with Donkey Kong, Cosmic Avenger, Mr. Do, Lady Bug and Zaxxon and loved all of them. So impressed with the arcade like graphics.
Glad I have one now
If we're talking about now, the one console I've always kinda wanted but never got my hands on was the Vectrex.
