James, I have no idea whether or not Marklin-LGB cares about customer or dealers feedback. As is apparent from the posts here, we are all willing to accept a little sloppiness in order to get our toys. Because of that, Marklin never gets the full picture of the problem. I suggest that every one of us should write the editors of the LGB club magazine every time he or she receives an LGB product that is not up to snuff, and we should do so regardless of whether or not a response is received. Sooner or later the message will get to Marklin.
They is also the issue of poor product documentation (users? manuals, parts diagrams, etc?). I am not willing to continue supporting Marklin-LGB if they are not willing to meet half way. I do plan to buy any new LGB rolling stock until I hear that things have changed.
