NameDrive exploded on the scene with an easy-to-use service and a different approach. If you kept your domains parked with them for one month, they offered to buy the domain for an amount equal to between 6 months and 8 years of the traffic generated.
More recently they have started a domain sales site - NDX Market - similar to Sedo and Afternic, with some attractive commission schedules.
NameDrive's services are very easy to set up and use. There are no lengthy waits for approval, and you can create one-click landing pages on demand. As with any service, these pages should accurately match the traffic coming to your site.
Their landing pages are attractive and flexible. If you view your domain portfolio settings ("Domain Portfolio" tab, and "Settings" tab) you will see small magnifying glass icons toward the middle of the page (between 'keyword' and 'header'). Click on one of these and you will see a preview of how your domain looks - along with a number of different options of how it might look. You can change the settings and see the result in real time, then apply the changes for real if you like them.
Examples of NameDrive domains include ToneBody.com.
