Yeah, that's not a bad deal at all. I pay $46 a month for internet through our cable company, Metrocast, if they would give me TV too for only $20 more, I'd do it.
All those little fees for the boxes, modem, etc, they do add up! Our modem is something that I still have to replace, we're still paying Metrocast $7.95 a month for ours. Originally, we had a bundled TV/Phone and Internet package and we were stuck with having to use their modem for their VOIP phone, but don't need to now.
I gotta get off my butt and buy a modem soon so I can get rid of theirs. I've probably already paid them enough on the modem fees to buy a new one or maybe even two by procrastinating on replacing it!
