The Starships Collection regular run, about to launch in Canada but already available in UK and US, releases a new starship model every two weeks. Called an "issue" because of the magazine that comes with the model, the ships chosen are based on those used throughout the history of Star Trek in the TV shows and movies. The cost of each is $20 or $40 a month if join the club that sends them out in pairs of two.
I joined the US version late last year and have to admit I am surprised with how much I liked them. I figured would collect the first 4 or so sets and call it a day but if the quality remains I might go for the entire 70+ ship run. Or until I run out of space to display which can get to be problem when talking about that many figures. Depending on model needs they ships are made out of a mix of mostly plastic with some metal and come with a stand that is specific to each ship and as long as don't drop on tile are very much more durable than would think. I dropped the Romulan Warbird down a flight of steps and despite multiple bounces nothing broke or scratched. Not willing to do the same unintentional drop test to the others (as of this writing have issues 1-10).
