As others have pointed out, Virgin (formally Telewest/NTL) supply a 
router for you, however it simply acts as a network bridge. You can do 
some poking about them - they're a Motorola Surfboard (or at least the 
one I have is) - whether they've changed supplier in the past few years 
I'm not sure.

The configuration on the CM is minimal; there is (or at least was last 
time I checked) some horrendously simply filtering supplied in the 
configuration that blocked ports 135-139 (Windows SMB), but not much 
else. You can't change the configuration of the box as its managed 
centrally by Virgin. You can however use SNMP tools on it to grab 
traffic stats to drive tools such as MRTG :-)

However because of the amount of configuration they don't do, it 
essentially means the ethernet from the back of the box is as good as an 
unfiltered pipe straight to 'net, and you are free to put whatever 
router you want - I've used everything from Linux, OpenBSD to recently 
having a Belkin and now a Linksys wireless router.

Essentially, choose whichever router is good for you.
