Sipura 3000 *does* support UK CLID, including withheld and unavailable
flags, as from around october last year.

You should find that most equipment that supports UK CLID also
supports US style CLID, so you shouldn't have any problems with US
style presentation on an FXS provided you use a US ring cadence (so
there is sufficient inter-ring delay to pass CID). Again the Sipura 3k
supports UK presentation when appropriately configured on the FXS port.

The massive thing in favour of the Sipura 3k solution is that it gives
you fail over in the event that your asterisk box fails for any
reason. I'd also recommend considering installing asterisk under
vmware or similar, so that you can reinstate the image on available
server at short notice in the event of hardware failure.
