Looking For A Rbac

I’m developing a site which will start out having some basic roles. Besides public visitors there is a member section for registered/authenticated users. These authenticated users will fall under the following roles: admin (only me for now), group admin, group members.

I’m debating if I should roll my own RBAC or try one of the following extensions: auth, Yii-user-manager, or Rights. Is there a “go-to” extension to use for RBAC? If I choose one of these extensions, how much of a pain is it to switch to another?

I’m pretty happy with the SRBAC extension.

Thanks. That extension seems pretty old. Are there any bugs or features you find lacking?

Not to my knowledge. If there were features lacking I amended them myself.
