I must admit that about the only scale I've never owned is S. I have modeled in Z, N, HO, O, On30, Std. Gauge, and Large Scale at various times, but never really had any exposure to S scale.
That said, I'm glad to see the S scale community being served once again after a couple of pretty rocky years in terms of production of their favorite items. They may be a small niche within the small niche that constitutes the overall "model railroading" community, but it's a very nice in-between scale for those who find HO to small and O gauge a bit too large for the space they have available, or who wish to create a large empire even if they have a significant amount of space.
As I see it, the important thing is that the hobby of model railroading flourish and be enjoyed, and I really don't care which scale the individual modeler may prefer. And I say that as the editor of a magazine devoted to a particular scale. Here's hoping that this new venture in S is a great success for all involved!
