    Wow, what a response! Thank you all very much. I'll try to combine my replies and reply in line.

    Yes, I really do have both options are available.

    That's one of the things that sounds attractive about DSL.

    The DSL is will be from my local telephone Alltel whom I have a low opinion of already. That's what's got me worried.

    From what I've seen, both the cable and the DSL options have a slower upload than download but that shouldn't be a problem as I don't plan on doing much of any uploading or web server.

    If cable, it would be Time-Warner RoadRunner or Earthlink over Time-Warner's cable network. Strangely enough, the Earthlink option is $8 per month less.

    You lost me here. I thought the DSL is always on, much like a network connection one would have at the office.

    They did say something about filters. I'm assuming that keeps the digital signal from blowing out your analog telephone devices?

    That's what I'm worried about, lack of customer service and technical knowledge, particularly on a Macintosh.

    That's a lot of downtime.

    It's probably slower at night when folks are home using it more.

    Check with Earthlink.

    I'm not sure either would win a prize.

    There is with Alltel DSL, the full regular version is $49/mo and a Lite version (256kbps download speed I think) is $35/mo.

    The guy I talked with about DSL made it sound fast but I didn't specifically ask him. The trouble with cable is that while it's available on my street and my house is wired, I never had it connected when I moved in. I installed an antenna in the attic instead. I don't watch enough TV to pay for cable. So they'd have to run the cable from the box in my front yard to the connecting point on the side of the house. They'd have to do that anyway if I was getting cable TV.

    Phone wouldn't be a problem. I fixed that myself about a year ago by running a new line from the attic. But for cable I may have to make another trip up to the attic. No big deal this time of year. Hate going up there in the summer though!

    No doubt the speed increase, even on DSL Lite would be much faster than dial-up and free up the phone line too.

    Thanks for your comments! Overall it does indeed sound like a crap shoot when it comes to speed, customer service and availability.
