In the last 12 months I have tried Netgear, Billion, Zyxel, and another make which I cant remember but was filthy cheap, and all worked fine. I dont honestly think there's a vast difference in any of the modern modems, they are all satisfactory. If you have a "problem" line, then some are better than others in dealing with noise levels. Some are easier to instal than others but again, no big deal.
Have a go, try EBay and buy a cheap one and play !
