Buying a template is like buying a finished painting and sticking it in a custom frame. Building a site from scratch is like painting your own painting.
Start Bootstrap is kind of like getting a paint-by-number. Some of the work is done, and the elements are there for you. If you want, you can just use the default styles and make it look okay, but if you're a bit more experienced as a painter you can make it look even better by adding some of your own style.
I definitely think that if you're looking for a nice, clean, completed template then head over to http://wrapbootstrap.com and check out their selection! If you're looking for something a bit more barebones, then http://startbootstrap.com is built for you! :)
Thanks again for all the good work and keeping them free.
That's why I am starting http://bootmystrap.com/ All changes in just one LESS file, using same classes as Bootstrap so if you do buy a theme it actually saves you time.
