Best Space Station Parts mod for 0.25

[Amtrak71]

Hi guys, I'm sort of new to the forums, but I'm not new to KSP. I've been playing for over a year or so, ad I always have tons of fun playing it.

I like to think of this game as a way to test my "building skills" instead of my flying skills...(hence why I use Mechjeb most of the time).

However recently I've come up to a small mind-block

I need some new parts for my K-S-S (Kerbal Space Station), and even though I have looked on Curse for some mods, I'm still not sure what's good and what isn't.

I'm wondering if anyone here can give me some good recommendations for Space Station Mods and or building tips.
