At the end of the day it is still a project game, and it is not exactly a sought after title. Williams EMs of this era are not really collectible unless they are fully restored. Bid Deal, Space Mission and Aztec have been on eBay recently and they don't fetch high prices (at projects). I would not pay $500 for a project Williams from this era. However, I've had no trouble selling restored Williams EMs. My restored Big Deal sold for $1400 - so there is a market for Williams EMs, but unless it is a Klondike/Jackpot or similar, it is not going to fetch a high price. All EM project games have dropped in price, but Williams is the poorer cousin. How much did the project "Captain Fantastic" sell for - over $1000 missing a backglass ?

The demand for Bally EMs - 1970 to 1977 is huge at the moment. I'd have to say that Bally has "overtaken" Gottliebs in terms of desireable titles. I had a feeling this would happen around 3 years ago.
