Kristine Marie Designs review for Hulk Product Options

Probably the best app with free features out there. They are quick to help install and fix any errors that may come up. Easy to use. These guys will even go above and beyond to help you with your site if they can regarding tweaks that have nothing to do with their app. For free, Could have a few things to make it perfect but there are paid apps out there if you want even more customization.
