comparison plugin

Hi Experts, Please let me know what are the best wp theme for Ecommerce affiliate site and it's related auto plugins

Hi All, I tried to bring my wordpress site Comparison Table as like this : http://www.toptenreviews.com/business/internet/best-shopping-cart-software/ But i need it in plugin , in Search of this had suggestions of WPcomparsion & Tablepress , here Wpcomparison suits out a lot but i have a doubt...

Is there a plugin or extension that would suggest products to a customer based on their answer to a few questions? Or can someone make this for me and how expensive will this be? I want to make a comparison site for brokers.
