Same theme, different machines!

[Harleyguy]

I was looking to pick up a Ring pachinko machine, and got in contact with someone who had one. When they sent me a picture, I was surprised to see it was an entirely different machine! The one he had has a VHS player blow the screen, and the one I was looking for had hands above the screen that dropped down during play to scare you. I've posted both below:

I have also been looking for a Jurassic Park machine as well. I read that it had a 3D screen, so I thought I would look into it. Double bonus since my son's favorite movie is Jurassic Park (he's 13 now, but I took him to go see it in 3D last year at an IMAX theater and he fell in love)

Well needless to say, I was rather surprised to find out yet again that there were different versions of the machine. I saw the 'volcano' frame version that has the claw at the top and an eye on the right, and the newer version that has the Jurassic Park logo at the top and a 'Red Alert' light on the right. I found someone who said they had one with the logo at the top, and when they sent me a pic of the machine, I was VERY surprised to see it was a third version! It had a different logo at the top, and a T-Rex head on the right!!! See below:

So here is my question: I know there are always different cell backgrounds for the different odds on the same machine, but who knows of any other machines out there where they feature the same theme but totally different playfields? I know when it comes to things like Macross and Eva they make sequels and offshoots, but I'm talking about machines like I talked about above.

Lastly, does anyone know which Jurassic Park features the 3D screen? Any videos of the three in play on YouTube would be greatly appreciated. Saw a few of the first two, but nothing on the last one, would love to see it in action.

Thanks!
