>> Thanks, the easy examples are examples only. I think, if the easy example works, than complex models should be good meshed too. Most important for complex scenes, where the polycount must be keeped low, but good looking - for example for rendering train / air plane interiors or large ships with many details.

If polygon count is so crucial, I dont think you need fillet on your models, it will increase the poly count a lot.
If fillets are important, you should try to use a smaller meshing angle (12-20), and use the 'avoid smaller than' option to reduce the number of polys. You'll have a much better visual/polycount ratio than just rising the meshing angle so high.
