I think you can get a centurylink modem used, factory reset it, plug in an ethernet cable from your computer to the modem, go to 192.168.0.1, login with admin credentials (sticker on modem) and put in your PPPoE username and password, call them to get it. I see some zyxel c3000z on Craigslist which is the newer one. I might need a new one as I am not sure if the bridge mode is working on the C2100T I have.
