If you are not fed up with Thomson SpeedTouch modems then you should go for the SpeedTouch ST330 USB modem. I used a previous version of this modem and found it very easy to use as there is no configuration or massive set ups.
Not only that, you do not have to contend with a NAT table/firewall, it is just a plain, plug and play (single user) broadband modem. Here is the URL:
