That would be the cheapest I believe; Comcast believe has the $19.95/Mo for six months in order to take advantage of the low price from either carrier and if you don't mind switching ISP at x given time, then you may get one of them and when the term is to expire, switch to the other one. In order to be considered a "New subscriber", one must bee off the hook for 90 days. So company X does not give you a nice-er price, threat with switching carriers, if they still don't then simply switch.
