Easy to identify files that takes large storage space.

Easy to use and gives immediate visual indicators of very large files.

It doesn't need one to turn off verification on OS X, like the discontinued open source alternative, Disk Inventory X

What is GrandPerspective?

GrandPerspective is a small utility application for Mac OS X that graphically shows the disk usage within a file system. It can help you to manage your disk, as you can easily spot which files and folders take up the most space. It uses a so called tree map for visualisation. Each file is shown as a rectangle with an area proportional to the files size. Files in the same folder appear together, but their placement is otherwise arbitrary.

Regarding price from product webpage:

Download GrandPerspective from Sourceforge for free or from the App Store for $2.99. You'll get the same app either way.

So what's the difference? When you get it from the App Store you know that it has passed Apple's review and quality control, you receive automatic updates, you help cover distribution costs and you support further development.
