Every time I pick up a classic Stern, it really pulls me in and I'm shocked how much I prefer them in the era. I just resurrected a mouse house Big Game and am shocked how quick that game plays. It had a few wear spots and plenty of damage in the bingo card area so I went real heavy on the wax to protect what is there and it flies. Those inlanes having metal instead of rubber just keeps everything moooovin!
Sorry - back on topic, agree with what everyone else was saying. If it's those three specifically, Seawitch is the easiest to find but all of these are painful on the pocket. I'd argue for Quicksilver as my favorite of the three, but I've only been able to play stargazer a few times. $ is my area is similar to the above quoted - I'd say always keep an eye out for a deal but these titles just don't pop up. Seawitch is the only one I've seen pop up in and around a decent radius.
