Quesion: Tattoo gun and ink help

Hey folks,

Self, colorado

I am looking to do a full body black out on myself. What would be the best ink to use for this? Looking to a vibrant black that'll last.

Lastly, have any tattoo machine recommendations ? I see several on offer up along with new ones, but im not sure what would be decent or what I should look for.

Thank you for any advice.
