There are obviously a number of factors that play a role in the decision for a high-end restoration, including fair-market value of the restored machine. But even when I think of a machine that commands a good price (restored or original) such as TZ, I also look at it being one that often may have a nice original playfield to start with. The cabinet may be faded, but pf wear isn't nearly as common as it is on other machines. Now MM, MB, CC, and AFM are all on higher ground when it comes to fair-market value. That next tier might include TZ, IJ, or such. I wonder how much people would pay for a NIB TAF remake as I have no doubt like MM it has its own magical number.
On another note, if someone is dressing up as Bryan Kelly for Halloween, how much beer should they have with them or should they simply ask for one at each house?
