DataCraft: I have used the draytek DV2910 before on a uns connection, they are very stable and easy to use. I have a spare one that is not being used if you want to borrow it and try it with your citylink connection.
Thanks for the offer of the test of the Draytek - might take you up on that when we get the line in.
More generally, if Cisco is recommended, how about this one
