Ok, it is not like a trial, you would have a contract with a StarForce enabled professional CD press, I doubt they would deal in less than 5,000 CDs. This is professional grade copy protection, and unless you are working for or starting a massive game company I wouldnt consider it.
As I have said before if you only want to make a few copies and you know the the name of the person you are giving them to the most effective copy protection is watermarking, just create a few text files with the persons name, then save it, then rename it to .dll or something, put this in a few places on the CD, then write a warning that it has been tagged. Now any copies made will still have there name on, so then if you can find a copy they have made you will know who they are. I doubt many people will still want to copy it if you know exactly who they are, it may be you never find a copy they made, but it would make they paranoid about it and therefore unlikely to do it. If the files are well hiden (or even better real valid files with there name at the end added using a hex editor) there is little chance of them removing them without ages of opening files on the disc.
