I've never seen Galaxy Of Terror, but I do know that Sid Haig is in it. He's Captain Spaulding in House Of 1000 Corpses and The Devil's Rejects!
If I can find a dvd, I'll get it.
I got Darkstar on dvd recently.
Starship Troopers 2 was about a new kind of bug that could take over people's minds. A group of soldiers are stuck in a small base, not able to trust each other. It had no characters from the first movie.
ST1 had a $105million budget, ST2 was $7million.

ST3 brought back Rico and also added in the long awaited power armour. Sadly, the power armour was laughably crap and barely used.
There's also a 4th movie coming out this year: Starship Troopers Invasion. It's a cg animated movie by Shinji Aramaki (Director of Appleseed, Appleseed Ex Machina, Gasaraki, designer (mainly mechanical design) for Bubblegum Crisis, Astroboy, Full Metal Alchemist, Genesis Climber Mospeada and one of the Naruto movies).
It looks cool, I'm going to keep my hopes up. Apparently it's a direct sequel to the first movie, ignoring ST2 and ST3.
