You should get a PRI T1.

The minute you get close to capacity on this line you will run into 
timing issues with incoming and outgoing lines competing with each 
other. This problem will only happen when you need it most, which is the 
worst failure case.

Unless your usage never spikes above 50% usage (counting incoming *and* 
outgoing) on this line you will regret not using a PRI.
