I use the Swiss AF 18666 (it's light blue with rubber coated tip). Should retail around $14-$18 around Peninsula area. When I was choosing, I took into account where I would use it (I would bring it out with me, so it should be small enough; those big and long-nosed types were ruled out), and the quality feel when use (some feel plasticky when compressed, this AF is nice and firm). I'm probably nitpicking, but I'm paying money buying one and it should last for several years. PM me if you want to see how it looks like
