Big Ben is not one of my favorites to say the least BUT being so close to you and also a great selling price I would go and look at it.
My advice to you is: Being new to this hobby and wanting an EM pin as your first, buy a single player pin first (Big Ben works),
get a schematic and learn how they operate. As you learn from that pin, you can also start learning & understanding the workings of
2 & 4 player pins which at times can be frustrating to fix at times.
Good luck, have fun and welcome to the hobby.
