I live in a rural area that has had DSL in the small town about 2 miles away. I never qualified for DSL until the phone company made some upgrades. I looked again at the price for DSL and they want $8.50 a month for the DSL modem rental or I can buy and unit from them for $250. I was told that I could buy my own DSL modem and the ones they sell are Next Level etherset. I can't find this "modem" on ebay or at any retail site. Is it possible to buy any DSL modem or do I need a specific one that matches their technology. Thanks.
