The script builder is just sick!! I've been playing with it last night and built a custom site and it's seems to be working.
Well you do need to know a little bit of html to understand what you're doing. You could pull it of with no programming skills and html knowledge, but if you do have such understandings, building engines will be a breeze for you. I think the developer has made sure to make it as easy as possible for people with no programming background be able to build their own custom engine scripts.
And the reward from this would be huge!! Just think about it. We all know that:
1. Google loves backlinks from customized engines
2. Google loves backlinks from authority sites
3. And most of all google loves backlinks from niche-related sites!
Just make a quick search on google in your niche and look at the first very few pages. See where you can place a contextual link manually (you'd be surprised how many such sites exist if you look carefully enough and experiment). Then build your script with script builder and blast away with turboweb 2.0 ! It's that simple!
I can bet that if you build even around 10 such links, they will be much more valuable than 100 web.20 on the most popular engines that everybody is building at these days(wordpress.com,tumblr etc..). You will be getting untouched+authority+niche specific backlinks! All in one package, and all of these backlinks just for you and no one else! Well except if you decide to sell the script you've built with script builder to someone else.
And besides I'm having so fun while using it. I feel like a senior developer, lol!
