Can you consistently beat this guy every game? Tough decision.

I have a list of about 3-4 machines I still want, and I'm always thinking about what will go first, but that decision keeps changing - I don't want any to go.
At least you will be able to buy another Gorgar in the future, but it won't be as good as yours.
If money isn't an issue give it to a relative or someone you know/trust, or swap before you sell it. If you don't miss it after some time, then sell it.

I've also thought about swapping and think it's a great idea.
