I just got my first HEP and it's a Williams IJ. I freaking love the machine and have probably put 40 games on it in 5 or so days. The reason I like getting HEP games is because if you are a stickler like I am in caring for your machines a HEP should last you a very long time. This obviously includes waxing the game every 300-500 plays at a bare minimum and also waxing the balls.
By the way, it's no secret why the game plays are typically low on a HEP machine. Usually, it's the same type of people who own HEPs and there aren't a ton of them out there. Obviously, to be able to own even 4-5 HEP machines we are talking a new Mercedes E Class. So, those guys own more than one HEP and last time I checked everybody still has only two hands to flip with.
Odin, digging your overall collection man. Would love to hear all the bells and whistles with every game turned on
