I have a few 2821's running the VWIC-1MFT-G703 WIC, which supports E1 circuits. One site is in Ireland and the other is in Germany. I think your best bet is to ask your ISP exactly how they are going to 'deliver' the circuit (framed/unframed, PPP/Frame Relay) and then verify with them which WIC you should buy. But in general, I think a 2811 should be fine.
Relevant info from one of my configs:
controller E1 0/0/0
channel-group 0 unframed

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
