Some good discussion and feedback in this thread .. just wanted to mention that a couple of comments made me think about  my current PITA in the DMD world  .. http://aussiepinball.com/index.php?topic=12788.0

"I think every problem ever logged was sorted out - eventually !" .. sadly not mine yet and very few suggestions  

"What ever the problem is, somebody else has had it" .. after a lot of googling can't find anyone mentioning this fault  

Just thought I'd throw it out there ..

Have to agree taking down the pinrepair guides was such a shame .. they had a lot of useful info
