I have used the Steren Tool and the Perma seal connectors for RCA and F fittings.

The RCA ends work fine, although they do not look stellar compared to some of the Liberty or Monster Cable ends. No gold plating and the color bands are very thin when the fitting is compressed.

The F connectors are OK and do look better than an augat end. One drawback to them is the length.... if you are in a tight cabinet they require more room.
