Do you already have it? YES
how much is it where you live? $30 at the house and abot $70 for three lines at the office with dedicated ip's.
do you like it? yes
does it work well? yes
i use verizon and had them split the line outside so i do not use filters on the phones and i can use the phone and the computer at the same time. the dedicated ip's at the office never have a problem. the one at the house drops out on some occassions. not as much now as it did several years ago when i first had it installed. most of the time, rebooting the dsl modem gets it back up and running.
a litle over 700kbs down and 125 kbs up. seems fast enough for me. eliminating aol was a good choice too. i don't know why i hung on to it or so long.
from what i have been able to gleam, you use whatever is available where you live. if you have choices, much better.
