I saw some die-cast models at the Landmark yesterday. What caught my eyes were the Bell 412 and 212 at 1:48 scale. They were in NYPD and LAPD scheme and looking at it gives me the urge to buy them and adapt the 250th (412) and 505th (212) color schemes. There were other models like the USCG Agusta Stingray (1:48), the Jayhawks and Canadian Cormorant both on 1:60 scale.

The problem I see would be the interiors to conform with the real thing.
