There are a number of incredibly cheap training providers around too. Some are okay, and some are just ripping off more expensive courses and providing skin deep and often incorrect information. These providers often plug their own exams, which is where the expense is finally incurred. Do your research and look for reputable and industry recognised certs if you're going to pay.
