This is an old thread, but since I'm in Bend this week and now there are a few cool spots to play pinball, I wanted to give an update...
There is a newer pinball place in Bend, OR called Vector Volcano and they have 8 pinball machines in good playing condition. Pay $5 at door for 1 hour of free pinball or $10 to play all day. Ghostbusters Premium costs $.50 to play, but the White Water, Dracula, TSPP, T2 and other machines are all free. They have ColorDMDs installed too.

Mountain Jug is near Sunriver, OR and has an AC/DC Luci, very cool place.
