I have very little experience/skill with tools and had never built anything before in my life when I built my UDS. Went to Lowes and had all my materials in about 45 min. The actual build of my UDS took less than an hour. I say build it yourself. Study the monster thread here, look at YouTube and have fun. It was important for me that my UDS be MINE.
Plus, like I said, I'm not mechanically inclined at all and I think it was a breeze.
