How do you think I feel when I see a 1/72nd scale kit?! Don't know how I ever managed them! Must admit, I do like 1/32nd and bigger, but 1/48th allows a lot of detail, at a reasonable size, without having to rent a barn to store them!
It's a pity aircraft kits aren't done as standard in 1/35th - then there'd be plenty of figures and vehicles to use in dioramas, large or small.
