I really like the GuideGuide plugin for Photoshop that really quickly allows you to setup guides.
Is there something similar to this in illustrator ?
GuideGuide is now available for Illustrator (CC+)
You don't need GuideGuide. You can use the canned Illustrator features.
You can also tick the "Add Guides" option to automatically create guides which align to the rows and columns.
Also, you can pull a guide from a ruler, and select the guide and define x and y coordinate (for vertical guide x coordinate, and for horizontal y coordinate)
