If they are in fact offering 2 body styles, 5 sills, 3 roofs, 3 ends 8 doors, 3 hand brakes, 2 brake systems, 2 coupler options, 2 cut bars, and 3 sill step options, then $30+ is in no way out of line. They also still mention a new truck on the N scale page.
Anything less than that I hope they're lambasted for being too lazy to make a separate N scale page.
