Mine used to be the same as yours. I now have an ISDN line and it is so much faster. When you are with an ISP that cuts you off every two hours it means you can get back on in seconds. I certainly wouldn't go back. I have no hope where I live of getting broadband.
I am with Freeserve Anytime. They have no problem with ISDN as long as you only use the one line. That still means it comes in at 64. I have Home Highway. I'm sure it is nothing like as good as Broadband but compared with the 24 I used to get it's bliss.
