Restrict Admin Page Access to Certain Users?

I have been searching around but have not been able to find a plugin that will allow me to restrict admin page access to certain users. Is this possible?

I have seen plugins that will allow me to not show the frontend of a page to certain admin users. But what I want to do is when a certain user account is logged into the admin, that instead of having access to say all 10 pages, they can now only edit 5. This way I do not have to worry about them messing up the more complicated pages.

Any ideas on a plugin out there that will solve this? Thank you.
