>>6487132There are a couple of ST TOS sets but that is about it. And most of them are long out of production.
Spock, Sulu, and Uhura are only available on the large sized/Enterprise Bridge set. It also comes with Kirk, but he's also available in another set (see below).
After that there is three mini-play sets, which have been showing up a lot these days in discount outlet stores like Big Lots, Ollies, and Magic Marts.
1. City On the Edge of Forever set. The blocks form the time portal and it comes with Kirk that is identical to the one from the Bridge set, along with McCoy and two Red Shirts (one black and one white).
2. Mirror Mirror/Teleportation Room set. Mirror Universe Kirk, Mirror Universe Spock, and a variant of Mirror Universe Kirk in translucent yellow plastic making it look like he's being teleported. Blocks form the Teleportor Room from the Enterprise,
3. Engineer Chamber: Two TOS Kilingons and Scotty and Chekov; all of which are sporting swords. Block set forms the Engineer Chamber
There is also a Klingon Bird of Prey model ship set that comes with the same Klingon from the Engineer Chamber set and an Enterprise model ship set that doesn't have a figure.
TLDR: you can get everyone but Uhura/regular Spock/Sulu cheap as they are the only ones who require you to buy a huge fucking set to get.
