As with all games, you need to take some time to play it and decide for yourself - don't let others make that decision for you.
I have a premium and love it - yes, it's hard, the flipper gap is brutal, but it keeps me coming back, and won't leave anytime soon (especially now with the release of the ColorDMD)
Again, as with most Stern games, it did need some adjustments out of the box - Slimer ass dragging, switch gap for the magna slings, flipper alignment, but its a great game once set up correctly (imo).
