My first pin which i still own today was Cirqus Voltaire. To this date i have done nothing more than replace batteries. So i am not in the camp that 25 year old pins are ticking time bombs and will need a lot of work. Especially in a home environment.
Of course it also depends on how it was used for the last 25 years. Heavily routed / or used in a home. And more important is who cared for it and how it was cared for.
Anyway my two cents is get what you want. I regret nothing from my first purchase because thats the one i really wanted. TOM is a gorgeous game and imo fun to play. I would just get one off of a collector who has shown it some love and taken care of it 
. And when the day comes when you do need to fix something there is Pinside who will help you if needed.
