if you are patient and mechanically inclined and ask for help here i highly recommend you do it yourself.

my first wheel actually came out perfect and is as good as subsequent builds. i wouldn't hesitate to do your first build on yours. myself or others will double check your spoke length calculation for you. i recommend supercomp dtswiss with aluminum nipples.

i would also recommend the cheap park tensiometer, i thought it was a great help at any rate. i can also summarize some other tips so you don't have to search the net for them
