So I take that's what the advantage of T1s are? I never understood that either as DSL can go faster then a T1 and significantly cheaper, but I haven't seen a way to combine the bandwidth for one IP. I've also seen DC3 connections from a few ISPs that are up to 20,000 a month. But still at a very poor bandwidth. I just don't understand what makes these different connections so special.

There is a difference, mostly in latency and possible b/w ranges.

You can get ADSL anywhere from 256k to 1.5M fairly cheaply. This will have an average latency around 30-40ms. Generally these connections are not treated as mission-critical by Qwest, and can have acceptable burps in connectivity.

A T1 line costs a lot more, and can range from 56k to 1.5M. These typically have very low latency (0-1ms). These have extremely high availability, and amazing uptime.

A DS3 costs even more, but is capable of b/w up to 45M (IIRC). Super low latency. same high availability. Common for large companies, and ISPs.
