Just discovered this forum, some great topics, but this subject interested me.
I have been using DesignSpark PCB since version 3 and now at version 6 and find it very usable. I think some of the replies above are really from the short evaluation time, to rotate a component simple select it (left click) and press the shortcut key R and it rotates 90 degree, just repeat for further rotates. As with most CAD programs the full options available are on the right click menu.
Many people instantly state there is 'nothing' in the library, but go to the Library Manager and the folders tab and even the old legacy components are available, but the best way is use ModelSource and many of the components from RS Components and their various footprints are all there.
If you can't find what you want then the Library Manger also has wizards to create schematic symbols and a very powerful footprint generator and these are combined to create your own component.
I found DesignSpark PCB when looking for a cost effective package for small business use, Eagle (free) for my requirements was too restrictive and the commercial versions I had to spend too much! The other CAD programs at that time had lots of issues being discussed on their forums, so I decided to jump in with DesignSpark PCB and learn the tool. It's not perfect, but quite good once you learn the ropes.
If anyone needs help with DesignSpark PCB I'll try to help, but I've only gone as far as double sided so far.
