I've had my Indy for about 12 months and really love it. I have only been into this hobby for about 15 months so have not played heaps and heaps of titles. I would say though that i rate my Jurassic Park almost as good as Indy.
What i like about Indy is i can just explain 1 part of the ruleset to someone who comes over and has never played a machine before (eg: hit the centre hole 3 times for multiball) and they can just enjoy doing that rather than needing to understand all the rules and a lot of people in this category reckon this is the best pin out of Jurassic Park, STTNG, Hook, Black Rose.
For me, as i said its only just better that Jurassic Park, but one thing that keeps me coming back to Indy is i've never come really close to completing all 12 modes in one game yet, so i love the challenge of that.
Mode start is an easy fix, swap the mode start stopper thingy with the centre hole scoop, since then i've probably only had 2 times the ball has bounced out.
If i was starting from scratch from two scenarios
1 If i had $5k to spend on my whole collection - i would buy 2 or 3 other titles.
2 If i already had a few machines and a bit of spare cash i would definetily have one.
My situation was that the machine was available for $300 (thats not a typo) so it was a no brainer, and this is unlikely to happen again....
