I owned one briefly (odds are excellent it's the one you're considering - I sold mine to somebody in Round Rock a few months back).
I shopped it out, played it for a few weeks, but needed to make some space so I sold it. I'd remembered it as a fun game that was pretty easy to play when I was younger, and that had really good sound effects for the time.
I disagree with the opinion that it's like an EM game with Atari sounds - the sounds are much better than anything Atari ever did, and properly tuned it's a fun/fast game. The sound effects are much like other Stern games from the time, such as Meteor.
I got bored with it quickly, as it was too easy for me. One of the reasons I probably enjoyed playing it at a 7-11 back in the day, as it was easy to win free games on...
Properly maintained, it's a fun/fast pin, and if you're considering it for your first pinball, you could do a lot worse than an early Stern game such as Galaxy. When it starts to get too easy, set it on 3-ball play instead of 5-ball, and crank up the feet on the rear legs to increase the playfield incline - that'll make things more interesting!
As suggested - play it a few times first, and see if you like it.
