Are there any good power armor mods out there? I'm going for something futuristic an run down a little, but I vent been able to find any thing besides the courier power armor.

Weird, I've never really noticed any power armor mods either. Usually just other types of clothes.

There is a couple of mods that I personally like. For example the MK117 Prototype Combat Power Armor Voiced and Weapons, VaultTec Power Armor or the T45d Power Armor Replacement

there loads just got to look hard enough theres even more than what i listed, but i recommend these mods there really nice and im sure youll find one you like. Theres even a halo power armor on this website called mk 177 like the guy above has said thats a really nice mod also  

Powered Power Armor in the nexus can make all Power Armors make sense (Even the ones from mods as long as they are tagged as Power Armor in the GECK). The Fallout NV version is perfect but the FO3 version is as buggy as Unity. (The FO3 version was abandoned for the NV version). Basically it puts the "Power" in power armor.

As RangerJosh said, Mk117 Power Armor is also good and is both available here and in the nexus.

There is also the Japanese Power Armor mods which are amazing and kinda bulky too.

There is also the Coyote Reflex Armor, I tried it and I liked it but I can't remember what was so special with it anymore. It still looks cool though.

There is also the Midwestern Power Armors or the Tactics Power Armor.

Last but not the least, there are a lot of Enclave Power Armors like the Colossus XV and the Enclave Relic.

Hope I helped.

TixEssence has a power armor mod in development although I dont think its been released yet

the good power armor is coyote reflex armor

Eu também tava procurando alguns mods de power armor, porém, não achei ;w;

I've been using the Legion Power Armor from this mod: https://www.nexusmods.com/newvegas/mods/44215?tab=description

I was just doing my first legion playthrough (out of at least 70 playthroughs), and had a pretty good time with this one

https://www.nexusmods.com/newvegas/mods/67936 I'm quite fond of this one purely because it aesthetically fits, and it affects leveled lists, which is nice in my opinion, I like seeing things integrated into the world.
