I truly believe that if your looking at the dmd era of games, hs2 and hurricane, the real need for hard tops is the 2k to 3k market. Games like demoman, judge dredd, fishtales, etc. Nobody wants to buy a one of these games and spend 1k on a new playfield. There are so many of the wms dmd games that are beat down that people would love a hardtop for it.
