I think pinside mail is down as I can't get this reply to your PM so trying here. This will also allow other to dispute my oppinion if they disagree.
LED's you say.. hehehe. I changed the whole color scheme. Check out my post here - http://pinside.com/pinball/forum/topic/batman-de-and-bop-leded Only real MOD I did outside of lights were the black flipper bats and the purple rubber. I wanted it night themed as after all it is Batman.
Gameplay - It's pretty easy. The music keeps me coming back though. My wife loves it though. You are right, it's mainly 3 shots with the 4th being the VUK that changes the reward for a ramp shot. I bought it at the same time as my Bride of Pinbot so they complement themselves well. If you like Batman you will probably like the pin but it's not going to challenge you by any means. If I want to sit back and see how high I can rack a score up I'll play it. if I want a challenge I'll see how long it takes me to get to metamorphosis on BOP. At $900 I would not think twice about getting it. I would not, however, pay the 2 grand plus though that i paid for mine ($1850 plus shipping). The funny thing is that when i have people over they will wait to play Batman while BOP is still in attract mode collecting dust. It's a great pin for party's and friends that are non-pinheads. A party with pin-heads, they will probably poke fun at you. We are building a kid fun game room so BOP would go before Batman so under those terms both are staying at my house for a while
Keep in mind I'm in the minority on this forum with Batman. Most here think it stinks. A couple of us like it though. If you are looking for a challenging pin you need to keep looking. If you want something affordable that you can still have fun with but not get a bunch of modes and tough shots then you'll be happy.
