Quoted from bluespin:
dashingdaryl This is a two player wedgehead, not a very popular title, and is probably only worth $500-600 if the playfield and cabinet are in nice condition. If you search this forum using the filter "find in this forum" you will see that this title has been offered on Craigslist for $250-350 with the backglass. The most popular wedgehead were the one player versions because they could offer more complex scoring bonus opportunities if there was only one scoring reel.
Thanks. As a pinside newbie, I never knew what a wedge head was.
