The Cane Creek C2 (if I remember correctly) was my choice for years, nice quality and moderately priced. Since I commute daily, in all kinds of weather, I ended up replacing my entire headset yearly. That was until I upgraded to a Chris King I got (new) for $80 on Craigslist. It's been in for nearly 5 years ago and it's still perfectly smooth with no indication of wear. One of the best upgrades I've made (the other is my wheelset; Velocity Chukkers/White Industries MI5 hubs), my mentality is to pay a little more for quality and enjoy more rides as a result.
