Just wondering what your opinions are on whether you think it is better to build a 3d printer or buy one. I know there are a lot of arguments going both ways, but I'm trying to get feedback on this.

Of course buying is more expensive, less time consuming, and easier. Building is more fun (if you like that sort of thing), more customizable, and cheaper. What are the other aspects of each that I am missing?

Have you bought or built yours?
