Sellware has been a great third party tool for us to use to connect NetSuite to Amazon/eBay. Unlike other connectors, it didn't require a random company going into our NetSuite account and making a bunch of changes and changing the look of the interface. Instead, it, relatively seamlessly, allowed us to accurately export our information and re-import sales and inventory counts without messing up anything within our NetSuite account. Additionally, customer service is excellent and anytime we have had issues, we have had responses and help right away. Two thumbs up for Sellware -- definitely the best solution we could find to sell on resell sites.
