Both. Get a t1-pri - this will give you high uptime, high quality  
calls and all the rest.
Then sign up with a couple of SIP (or IAX) providers and use them for  
cheaper
international calls and to provide some extra capacity (100 users  
could fill
your t1). Make sure your dialplan fails over to the PRI when your IAX  
providers
are both down or your internet dies.

The additional cost/hassle of doing both is quite small and it gives you
more flexibility.

Try and buy your T1 from someone other than your ISP.
Otherwise when they go dark you lose _everything_.
We had an incedent a year or two back when BT had a fire in the local  
exchange
cable duct. The only thing working in  the building (actually half  
the city)
was my NTL E1 delivered over glass! (Mobile network got busy too !)

If you have to chose go for PRI.
