Roles Manager

I was wondering if there is any simple Roles and Capabilities manager available for 3.0. I’ve tried a few others without success. The Role Manager plugin almost works but seems to have a bug in 3.0

Role Scoper works but I’m pretty confused on how to use it.

All I really want to do is hide links and show pages for certain users. Theres another thread on this but what they need is a little more involved.
