I started on an old project a few months ago. About 20 years ago my Father and I started collecting Z scale. Recently I have been putting together a Noch Cortina layout. I really like this layout but have not bought the form yet. I do have a track plan and using the Marklin track I got in a starter and expansion track set plus what I have collected over the years I felt it best to continue the track plan in Marklin. I know there are other cheaper makers out there but I'm about 3/4 of the way done collecting. I also try to find the best deals on track too. So my question is this... Other than Ebay is there another site that would be recommended for collecting cheap even used Marklin Z track? I would prefer to keep it in the US too if possible. I have tried buying from Tranz and Quality trains on ebay but was not impressed. Tranz took too long to ship, and shipped everything separately. QT lost my order and eventually refunded my money. I'm looking for different quantities of 8531, 8562, 8563, 8588, 8591, 8592, 8939. Any help would be great.
