It is worth looking on eBay. You can often pick up cheap unregistered copies of Elements that have come bundled with a product (Canon cameras for example). I paid less than $30 for my Elements 2 to a guy who'd got it with a scanner and who already had CS2. Elements does everything you will need to make you shots a.net ready and is a good program to start with.
Check also that your OS
is capable of running the software. Many newer products will not work with older OS
like Windows ME and require XP
