I think the first question you should ask myself is whether or not you really *need* to do a pharmacy technician training course. It is completely possible to study for the certification exam on your own and pass it without going through an official training (which I think can be quite costly). I personally purchased a couple of review books from Amazon and also studied the top 200 drugs. I would also recommend brushing up on some math skills because it seemed a lot of the exam was calculations.
State to state laws vary, but my state does not actually require certification. They require technicians to be licensed - a painless process involving $10 and a background check, regardless of training. You should consult your own state's laws regarding their requirements.
Finally, one benefit of training programs I have seen mentioned is that many of them do offer job placement assistance after you complete their programs. If you are concerned about finding a pharmacy job, that might be one upside of a training program.
Good luck!
