I was looking at a GW just this weekend, it had issues. The sound didn't work, it was all muffled when the guy turned it on and then during game play didn't work at all. Also it would keep putting 2 balls in the "launch" area as soon as u hit start. He was asking 400.00 what you guys think? I was thinking on offering 300.00 just so my daughter could play it. I tried it out it seems pretty cool. That air Siren and topper woulda make it a lot better, but no sign of either so far.
