Huh? Slow ADSL is 384Kbps minimum, 1.5Mbps maximum. Roadrunner is
like 300KB/s ~=~ 2.5MBps. Surely you're not forgetting the factor of
eight?
Two years ago Roadrunner wasn't like this, but nowadays it really
is something like a 2Mbit connection. Consider what a T-1 still costs.

True, and the latency was abysmal a while back, but the peering
arrangement really helped. The main thing I notice is that latency is
really variable, 30-200ms, and it never steadies out.

Unless you have something lovely like PPOE.

And you get to receive the Big Middle Finger from both SWB and the
intermediary and sometimes even the ISP.
Another problem with Roadrunner is that their DNS servers stink,
and sometimes like to pretend that the world doesn't exist. Occasional
inexplicable total loss of routes to certain hosts for a minute or so at a
time. Their SMTP server goes nuts and refuses connections on occasion.
Then, most recently, their joyous mailserver behavior w.r.t. the local
mailing lists.
It's a 2Mbit head-in-a-dark-place connection. The question is, if,
after going through the hell of installation, that's inferior to a
much-slower-but-more-professional ADSL connection.
(Of course, a static IP fast (1.5-6Mbit) ADSL connection beats
all, but that's pricy, and you've gotta be lucky about line quality.)
