CenturyTel is fair, I really wouldn't recommend it for most people though.
For one, you have to buy a modem ($60) which they will only buy back for $20, naturally. I'm guessing they just turn around and sell it for $60 again... For another, it's $30 for the DSL + $14 for the phone line. As a product of modern technology, I use a cell phone for all phone calls, and so a phone line with the normal dial-tone is useless to me. I even talked to a couple supervisors, because I know for a fact that DSL does not require dial-tone services to function, but NOOO, I still had to have a basic phone line. Also, the bandwidth is only 512/256 (for the $30).
For roughly the same amount monthly, you can get 3000/something cable service from TimeWarner or Grande, neither of which require you to buy the modem (or pay to replace it if it breaks).
