I think theres better in between solutions. Magento is a full featured amazon type site. Its a beast on its own. If you want a simple store, you can do yourself then look at spree. If you want something simple and fast, out of the cart look at shopify or yahoo ecommerce solutions. I think theres more to running a store than just hosting code, such as worrying about payment solutions, and overall security. Thats why I would first suggest paying for something like shopify or yahoo, and see if you can generate the business needed to rationalize going with a solution like Magento.
