You can try Designer Pro X10 for free. All the features are enabled in this trial, but it does not include the third party plug-ins (such as PhotoLooks) and only a selection of the templates can be edited. Previews of all the templates are included so you can see exactly what you'll get if you purchase - the previews are shown in the Designs Gallery in red folders and marked (preview) and the editable templates are shown in blue folders and marked (example).
