This is an interesting one.  Hasbro's Tantive IV playset is a big hallway that can connect with itself so you can expand and make a whole ship - but sadly, there's no actual ship to be had.   There are opening doors and a reissue of the previously released The Vintage Collection Rebel Fleet Trooper with requisite changes, but that's a good thing.  You'll probably want 2-3 of these when they come out very early next year.

It'll be $49.99.  You can order yours at Entertainment Earth, and also Amazon... or the toy sellers that don't kick us back a few pennies or dollars when you click those links and place an order.  So we suggest those links.  It's called bias.
