I use cable internet (I got it because of the no contracts). I pay $44.95 a month with SoCal TimeWarner Roadrunner. Once I move, I will be using AT&T Broadband. Since I have my own modem, I will be paying $34.95 a month. It's not that bad. It doesn't get any cheaper than $30 for most broadband services.
really really don't wanna upset no-one, but I use Bell Sympatico here in Canada (phone company high speed) and I pay $39.95 CANADIAN a month, which is about $22.72US, or about 15.60 British pounds..... with download speeds of up to 1Mb/sec (Ha! fat chance of that!!)
Still, it has never given me any probs with slowdowns etc..
