The Easton is an excellent stem, and a steal at $19.99. However, at that price, Nashbar has only one (slightly odd) size available. Are you absolutely sure you want a 110mm 0 degree rise stem? That's going to be a pretty radical change from what you've got now.
The Bontrager is a fine stem as well, plus you'll have the advantage of trying out a few different sizes at your LBS. Getting the right size stem is more important than who manufactures it, IMO. In fact, depending on what kind of riding you do, I'm sure your LBS could fix you up with a perfectly safe & functional generic stem for $10 to $15.
