My company dyes yarns in over 150 colors.  Barn2's Product Table allows me to present the customer with a comprehensive look at all of the colors.  They can conveniently select their palette without unnecessary clicks and paging.  
It just works.  But the best part is that if I have a question or need to add a feature such as a wishlist, Barn2 has done the work of figuring out what other plugins will give me the functionality that I need.  The plugin is first-rate, but the support is out-of-this-world good.
