The fact is that if you consider the game a permanent fixture in you home, and you can afford it, it is not difficult to justify a HEP restore. On the average, restoration costs about as much as a NIB machine, and when it is completed, you essentially have a better than NIB machine. The difference pretty much being what you had originally invested in the game prior to restoration. So it should not be considered a financial investment but rather an investment in years of enjoyment playing a favorite machine in the best possible condition.
I have a number of HEP machines. But my favorite HEP machine is my CFTBL plated in black nickel. Unfortunately the gallery photos of the restored machines are no longer publicly available on the HEP site.
Whatever game you choose, you will not be disappointed in the final product.
