I have played all of them. If your too young for the music pins, then BM66 is out as well, right?
I think the two best pins to play are Met and Aerosmith. I'm not an AS fan but have to say, that game is fun.
Others,can weigh in, and will, but I also think these two would have good value down the line as well when and if you would want to trade. You can see how popular they are in this thread.
Good luck on your choice.
