I've been using PTHPasteboard for awhile, and it's a very good clipboard manager, and it's free. I've tried it and some other clipboard managers, but found this one to be best. Others don't offer as comprehensive clipboard editing. I like the contextual menu feature on this better than the others. It's more intuitive than moving the mouse cursor to the side of the screen or some such activity necessary in other tools.

I paid up for this in a hurry, as the $20 price expires tomorrow (May 31). I believe I made a great decision, but time will tell. I've only used it about two weeks...

So far, it's a 5 star utility.
