Another vote for WPT. Picked one up recently and it's a great game for the price. Deep rules, fun layout, drop targets galore, two games in one (drop target poker vs ramps Hold'em). Ton's of value here.
WCS94 - Broad appeal, fun shots, simple rules but never gets old to defeat Germany in the final. Good tournament pin also with even scoring.
Have to totally agree with STTNG also. Overall I rank it as the #1 pin of all time. Theme integration that is the best ever (yes it tops LOTR in this regard). The only pin that might come close on theme integration might be TBL but it will still be missing the custom speech from the actors. It really smokes everything in it's price range and even pins costing 2x as much.....IMHO.
