I am such a fanboy of this game. I remember when a few lightbars became available several years ago. I paid what seemed back then a fortune for the lightbar and then the glass and strip set to finish it. I think I put like $500 for all of it. Since then I've been look for the S2000 version, just because. Lo and behold I went to a local dealer that was blowing out some S2000's and found one for $100. It needed some work, but the glass and strips were in good condition, it also had no mpu, but I had the software so that was not an issue. It also had a multidenom touch box, which is kind of rare on 3 reel games, at least for me.
The artwork is darker on the S2000 version, but other than that, it is nearly identical. Also the lightbar on the S is attached to the cabinet with brackets, on the S2000, it is attached to the glass with adhesive.
