I had a pair of Alex wheels on my bike and they were crap. I had the trued and retensioned at my LBS, and I trued them several times as well. They simply suck.

I found a pair of Mavic Open Pros used on Craigslist for $100. They are bulletproof. I've never had to touch them in over a year of pothole crunching, curb jumping commutes. And this is on a fully loaded 30# bike with a 185# rider. You can get them new at Performance for ~$200.
