There are many options for purchasing pens. If you're going for value alone, try a "stick pen". I personally prefer the click style because I tend to toss pens that have lost a cap (hate those ink marks on the inside of my purses!).
Here's a video with first impressions of the 4imprint style that I currently use (made last summer upon receiving my first order).
