We also have a T1 (1.5mb) setup because I am moving everyone to VoIP on the 16th... It's really snappy for browsing but it's not really good for downloading large files. It will be perfect for our phones though. Because our VoIP is going through the company that provides the T1 we only pay $100/mo for it. Otherwise it would be near $400...

A 100 meg connection won't necessarily kill a T3... A T3 is usually a direct dedicated connection to a major backbone and 45m/45m with extremely low latency and packet loss. Like T1's they are extremely reliable but you pay out the arse for it... Expensive but for applications like Business VoIP and critical apps that reply on the internet they should be your only option.
