Saw this on Kijiji today, I wonder why the seller didn't post a price. Did you see it in person? It looks like it's in great shape but I can't see below that kick out hole. That's the spot I would expect to see some worn paint. If there was no planking, no worn paint and it is mechanically sound, I would offer 700. I would say 800 to 1000 but I just don't see this being a super-fun game.

There are other symmetrical layouts that are way more interesting than this. For example, that Jungle Princess (2 player version of Jungle Queen) in Calgary has worn paint & planking but because it's such an awesome game, I would have absolutely no problem paying $1000 for it. Mind you, I'm a sucker for drop targets...

Who knows, once you have a closer look at it you might find that his asking price is reasonable. From the photos it looks like he takes very good care of his stuff.

The only other areas to check for wear would be in front of each slingshot and in front of (and under) the flippers. I didn't see anything of concern in the photos.
