Another vote for a. I would try to build the wheel and if for some reason you can't get it correct, take it to your LBS for a wheel true. I love building/truing wheels, especially my own wheels. I just sit down and take my sweet time with them. Same when I volunteer at the Co-op. I like truing wheels at work, but for some odd reason, it isn't as satisfying. With that all said, our shop only charges $8.00 for a wheel true. Building a wheel is $45.00 for labor plus parts. As you can see, it would be a lot cheaper if you lace it up first.
