I'm building up a bike for the first time, although I've done a bunch of maintenance over the years. I need to choose a headset, but despite reading a bunch of user review I'm not sure of the real-world advantages and disadvantages up what I'm seeing.

I'm using the Nashbar aluminum mountain bike frame and 1-1/8-inch threadless rigid fork: Nashbar 26" Mountain Bike Frame and Nashbar Rigid Mountain Bike Fork

The frame needs a standard 1-1/8-inch threadless headset. I verified that the ID of the head tube is 34 mm nominal. The bike will be used for all-weather commuting/utility cycling. It will be used with a front fender, which I expect will keep most of the crap out of the lower race. My goals for this bike are more durability and low-cost than low weight, but probably don't need the heaviest duty headset for how it will be used. I would like it to seal relatively well, but don't mind rebuilding the headset occasionally.

There are several choices in the $20-30 range. I would consider spending a bit more if it comes with a big jump in quality, but I have no idea if there is a meaningful difference.

I have a Ritchey Logic Comp on a road bike, and it's been perfectly fine through 4,300 miles or so. It takes some sort of cartridge bearings, which might be hard to find or expensive when the time comes: http://www.amazon.com/Ritchey-Logic-...c+comp+headset

The FSA "Pig" is cheap, has glowing reviews, and is reportedly very strongly built, but it's also much heavier than the competition. It appears to take standard bearing balls. Maybe overkill for me? Amazon.com: FSA The Pig Headset

And then there are a bunch of other choices.... Anyone have a favorite?
