If Wh20 was in mint condition then it would be a diffrent story. I have a perfect wh20 with clear coated playfield all new plastics ramps etc and fully chromed trim. This would be the only way to compare a NIB Stern to a Williams from the 90's on a like for like basis. As far a play goes I've not yet got to play GB hopefully not to far away. Wh20 has a very unique layout and ruleset not very deep but makes use of every shot and a lot of variety every game. I think it suits a collection with at least 3-5 games at it brings something diffrent. Would I have it as my only game, not now that I own an AFM. That being said I would not sell my WH2O to fund a new stern. Firstly I can play them on location whenever I want so not desperate to have one at home. So I would only look at older Sterns that are not readily on location such as x-men or Metallica.
