I currently have an Amazon Webstore.

I signed up for an Amazon Webstore so I could make an easy transition to selling my items direct on Amazon.com

This webstore is a complete nightmare. You can't customize anything but these widgets that are not in the areas that really need to be customized. Using this is a complete nightmare.

I have created 2 Yahoo Stores and I found it so easy to use and I am thinking of starting another, but I don't want the limitations that Yahoo imposes. I have looked closely at Volusion and Magento.

Can anyone give me an accurate comparison of A Yahoo Store, Volusion, and Magento

I will need to add 2000 products within the next 2 months and I am looking for something very robust and will be able to grow with my sales and company.
