This is one of those instances where you can have your cake and eat it too. Save a lot of cash and still relatively restore a pin to its former glory. Is it going to look new, no. But it can look damn good.
Here are three EM's (still finishing up 'Big Deal') that I have relatively little $ investment in (though a lot of time). I get compliments on how they look and play. Several folks have made significant offers to purchase which I have declined. Mainly for two reasons. 1- I know how solid they are play and condition wise. 2 - As some folks have already pointed out, I get a lot of pride out of knowing I brought them back from the dead.

Also I have several SS pins that have been brought back to life for less then half the cost of a repro PF. Gottlieb Victory being the most recent example. I have yet to post this restore.
