I've worked as a Tech for ~2 years now in a retail setting, and am starting Pharmacy School this fall, so here's my 2 cents:
Depending on your state, you may need to be nationally certified (through the PTCB) to even step foot in a pharmacy. But some states allow you to work as a clerk/cashier without certification. Regardless, I would not advise dishing out thousands of dollars for a job that pays only $9-10 per hour starting. Obviously it economically makes no sense, but also I guarantee that you would learn more starting as a cashier in the pharmacy that any program could teach you. The profession is a very on the job learning experience, for both techs and pharmacists alike.
Go to any of the Pharmacies in town and ask to speak to the Pharmacy manager. Explain to them you're interested in being a technician and want to know if they are looking to hire. The best qualities to have are experience with customer service, and a desire to advance in the profession (be it tech, Pharmacist, or anywhere else in the medical field). Many of the retail chains (CVS, Walgreens) will pay for your training and certification. An independent may do this too.
As far as Haybusa's picture that he paints of working in a retail setting... there are ups, downs and politics no matter what setting you work in. Some people hate the corporate demands of retail, and some hate the politics of a hospital/inpatient setting. Personally, I have a love/hate relationship being in retail, but above all I enjoy the patient interaction, and the accessibility people have to my services. If you have issues communicating with people who may not be in the happiest of moods coming from the doctor/hospital, then you'll be in for a rude awakening. It most definitely does take a thick skin and an assertive attitude.
Pharmacy is a small world and and being a technician is certainly not a dead end if you always look to get your foot in the next door.
