eBook 3D Wizard  (Highly Recommended)
This one is my favourite. Out of all the eCover software we've reviewed, this surely gets the maximum points. I chanced upon this wonderful software which works in somewhat similar way the other software listed above, but has loads of other features. It can create covers for eBooks, Software Boxes, CDs, DVDs and also for Floppy Disks! 

I like the way the user has full control over the eCover created - you can edit right from the cover size, to the graphics used to the profile of the cover. The best part of this software is that once you have selected all the options for your cover, you can rotate the 3D image of the cover and get as many variations as you want. This ensures that all your covers have a unique look. There are tons of templates available on the site, and the software also gives you options to create your own graphics if you want. For a demonstration of the different types of eCovers you can create and to download a trial version of the software, just go to www.ebook3dwizard.com. John Flynn, the developer of this software, also has an excellent eZine which offers resources, eBooks pertaining to creativity. You can sign-up for the eZine at http://xerostar-times.com.)
