Well those statistics kinda contradict what i said, but over the 5 purchases Elvira was on average some $129 more expensive. For availability, Diner is the most rare... i guess Elvira is a cooler theme- im a sucker for monsters and tits also.
Have to admit, if i were you standing in front of both those machines being told i could have one of them... Elvira would be what id pick, even knowing that i might not get a chance on a good Diner ever again.
On those stats - average price on old momster tits $2360
