I read the chapter in the Zinn book (several times) and built my own wheels for my fixed gear. I had ZERO experience and they haven't blown up yet. It's not rocket science if you can read, follow directions, and take your time.

Truing a wheel is the part that frustrates you- making sure it's set on several points. Lateral and Radial true...of course, radial is the one that'll give you fits.

Good luck
