If it helps Dan, I sold a 1978 model cocktail cabinet, in very similar condition to a guy who wanted the original look n feel, it had only 3 games onboard and he was happy to pay $700. Because it cost me alot less, i said $500. He was verry happy.
I then bought a 1978 one which someone had added the 48 in 1 board etc, and when i sold that, I had people lined up wanting to pay $700 plus.
Dont underestimate the original old age to it, some people want the 78 or 80 whatever year model orig cabinet n carcass, cause it brings back memories. Alot of people dont want 2012 build cabinets.
Do it up n u shld get top dollar either way. Maybe things get more money in QLD ? but hope it helps.
