Nemesis: Lockdown Expansions Worth Getting?

I am thinking of purchasing Nemesis: Lockdown and saw some expansions from the original Nemesis. For those who own it, how well are the base expansions integrated into Lockdown, since I know they were originally made with the base game in mind? Do you think they are "worth" getting, or do they not add enough content to warrant the price?

For context, I've played the original Nemesis online and loved it. However, it is quite difficult to find a physical copy of it where I live so I decided to get Lockdown instead since I heard it plays very similar to the original game with minor adjustments and added difficulty.
