I have two Jags and one cd unit. One of the Jags is new in box and the Jag/CD setup is my original system from back in the day. It still works flawlessly.
I bought two Pro Controllers back in the day and use one regularly. The other is stored away as a backup. Personally, I prefer them over the standard controllers.
I have one, so I'm not interested at this time. However, it is a very unique system to have and collect. Lots of fun! Surely someone will be interested.
