i'm south of wilshire on veteran. i've seen speeds on kazaa as high as 140k/sec. case of command sucks, it uses homepna or something through a single t1 on an entire building, bunch of my friends had it, its just straight horrible. plus no way to get around the firewall on that.
the only thing that could possibly be bad about dsl extreme, is if their dns servers crash, well you should ask others how often that happens. mindspring, occasionally we'll have a 1-2 hours outage (maybe every 3 weeks, its gotten better as the year has gone on)
