I'm sure this gets asked a lot in these parts, but I'm currently running an Ubercart install on drupal6 (non-dev releases) and I keep running in to little problems that are making me want to switch to a different platform. I've used magento before on some client sites, but that is way too heavy for what I'm trying to do. In fact, I feel like drupal might be a bit too much, as I'm only selling a few products (2-3). I was contemplating upgrading to d7 and running Ubercart again, but I hear d7 is even slower than d6.
So my question to you, seasoned ecommerce veterans, is there a pretty light-weight ecom solution aimed at only selling a few products? I would like to have something that has link tracking, google analytics integration, shipping options (USPS/UPS), and authorize.net integration.
I don't need a giant catalogue of products. In fact, I'll probably be customizing each product page sepperately. I have been poking around for a few days and am looking for a push in the right direction.
