Dix,
You right it really is a good price and oddly it took me an hour to track them down at that price. If your vigilant it can really pay off sometimes. As you know you can typically find them around $125 each. Here is your link and yes they are still available.

As far a true-ing up your wheels, I would talk to Matt at BuchananSpokes.com (around since 1958) 626-969-4655 ext. 10. They are cutting some spokes for me right now.
