I've picked up another Star Wars Action Fleet Naboo Hanger on eBay for pennies. The two Hanger sets can be placed side by side or opposite each other to produce a larger combat arena.
The seller included a Dr Who Universe, Judoon Patrol Ship, pictured below. This was an unexpected bonus. The cyclindrical Patrol Ship stands around 120mm tall (the figure is 35mm) on four detachable legs, can be removed from the scenic base. It makes a great piece of instant pre-pianted terrain for miniatures from 6mm to 28mm.
