Hey Bruce,
In terms of a better stylus, I'd suggest:

Anything that is "Wacom Penabled" will work on the eDGe. Note: Wacom makes one with an eraser on the other end (for $5-8 more), but at present the eraser does not work on the eDGe (although at some point in the future it would be nice if they added that functionality).
