When our Road Runner internet jumped from it's great introductory rate to $45/month, we started looking into other options. From what we could see (between Time Warner, Frontier, and ClearWire) $45/month was a pretty normal price.
We were complaining about it to our wise friends B & H, and they told us about Road Runner Basic (it's not mentioned on their website...). It's a LOT cheaper than the regular Road Runner, and the speed difference is almost unnoticeable (you would probably notice if you like to download big things...like "Ben Hur" or something). Road Runner Lite is an even slower, less expensive version than Road Runner Basic.
Even if you combine TV/phone/internet, I think that you can request RR Basic and get a better deal. That's all I know about that.
