I've used a Belkin (with ADSL though), and found it hassle. It disconnected itself once a day or so, and sometimes overheated (it had plenty of ventilation).
At home I have telewest broadband too, and have a Netgear wireless router. It works brilliantly, and was a snap to install. Took me about 5 minutes from taking it out of the box (granted though, I'm not a beginner).
I've had zero issues with it. Can't fault it. It's up in our loft with the other computer stuff, and I get a fairly strong signal with my laptop down in the kitchen, 2 floors down and on the other side of the house.
