I have been out of the collection business for well over 5 years now, and have only purchased one in over 10 years (my currently restoring Centaur). I recently did a review of what it would cost now to rebuild the stable of 10 pins I had before I sold them all off:

Don't know if anyone has ever done the same? Just the games, not the mods or money put into them afterwards. All old prices included shipping.

Here's my list:

Fathom (700) - current 3500
Medusa (700)- current 2000
Strikes and Spares (600)- current 1000
Eight Ball (500)- current 700
Voltan (600)- current 2000
Black Knight (300)- current 2200
Flash Gordon (800)- current 1500
Black Hole (800)- current 2000
Frontier (600)- current 2400
Seawitch (400) - current 2400

Seems prices have gone up a little.

No no, it's definitely not whining if I agree with you. Most of mine were originally bought back in the late 90s and early 00s. In fairness, I did sell the Fathom at 2400 when it left.
