I realize that some of you don't need or even carry one, but I personally, feel naked without it. Hunting for a quality replacement eventually led me to the PBW (Portland Bicycle Works) web site and the sweetest 87 grams of polished aluminum and bamboo I've ever laid eyes on.

The head and lever is CNC'ed aluminum and the tube looks to be high grade 6061T6. A little keyboarding will land you one for about $35. Behold the Poco:
