Welcome to the community. You have met some great members in the above posts but you could always buy a phone off craigslist or ebay. Your make sure your local carrier runs the ESN number to make sure it can be activated once receive it. Also you can check out android.net its our sister site and we have a whole section for selling used phones over there. Might be worth a look but good luck tho. Hope you can do some reading up on android development. Feel free to make yourself at home.
