Quoted from NickBuffaloPinball:Not a bad idea to try and snag two pins if you have the room. Will help solve your original problem of getting bored of STTNG.
Yeah, seriously. Not all "A-list" are worth the money to every player. There are tons of hidden gems, or some great system 11 pins out there that you might be able to grab two for that kind of money. You should make the trek to pinballz in Austin and try out some bang for your buck lessor appreciated or older (non dmd) titles to get some actual playtime before you would buy.
