Four or five years ago (before pinflation), I had a hard time selling a very nice one for $1100 (no bites plenty of lowballers). I actually ended up selling the 9.5 backglass to one guy for $400 and the machine (with a spare trashed glass) to someone else for $750. Today for my remaining nicer one I wouldn't take anything less than $1900 (perfect original cab, which is unobtainium on SYS11s). It's not for sale, btw.

Also, it's as fun a game as Whirlwind, which I also own. The ramp shot on WW is harder, but ES has a more unique and very fun layout (WW layout much closer to FH, which kicks both games asses). ES has a better theme than WW, it's 'bitchin.
