Go for it, doesn't hurt to check it out. You might be able to pick up some used equipment, too, even from practitioners who have upgraded and want to get rid of their old amps, etc.
Using the wrong protocol definitely can cause people problems, but in vast majority of cases when something does go a little off it's reversible. Remember, it's not really doing anything to your brain, just providing feedback that your brain is using to make its own changes. Not saying you don't have to be careful, but in most cases it's as easy as putting on the electrodes and letting the program rip, once everything's set up for your particular situation.
Good luck! I mean, when we take all these drugs & psychoactive supps, what do we think they're doing? They're temporarily changing the brainwaves. Much better to train your brain to change them more or less permanently. Then ideally you don't need the drugs. ;-)
