Experiences with hackerspaces / makerspaces?

Hello, I'm looking for a place where I have access to machines such as mills and routers for my current project, and maybe additional equipment such as hoods and laser cutters for other projects later on. There appears to be a number of such spaces in the area:

Null Space Labs

Mag Laboratory

Hex Lab

Hackerspace LA

The Lab

Does anyone have any experiences to share regarding these or other spaces?
