I have also built a number of wheels/sets with good results. I use a simple truing stand and dishing tool. Indeed it's not rocket science, and with the guidance provided by e.g. Sheldon you'll be fine.
But there are more variables to lacing and tensioning than what is listed in the standard guides. And FWIW in my experience the real quality is not in what to do (the plan) but rather it's about how well you do it. Science and craftsmanship melt into a form of "art" that is wheelbuilding. And hence I have some nice wheelsets laced up by Pro's too.
Some of the advice I was given for my first attempt: get good tools, take your time and stick to 3x lacing and brass nips (it's stronger, easier and more forgiving). And FWIW2 my results improved notably when I started religiously stress relieving the wheel under construction. I use a pressing technique with the spokes resting on roll of ductape.
Go for it!
