Just wanted to let everyone know I just received my Penabled Wacom pen from Amazon, see link below. It was 19.99 (US). It works with the eInk side perfectly, is grey and black, better matching my PE and, best of all, fits exactly into the pen slot!
As the regular pens are not being manufactured anymore for Entourage, this is a great "back-up" pen if you are like me and leave everything in the wrong spot.
