I have used Billions for a while now and I find them resonable. Recent firmware has caused some issues with VOIP and wireless, and so i got a seperate router for Wireless network.
My previous modem best Router was WRT54G (this is still a fav) but you need a modem to go with it. I replaced this with ADSL/Wireless all in onw WAG54G v2 biggest mistake i ever made. I have a very very long thred on whirlpool on this trying to get Linksys to fix things on it. Eventually i switched to Billion for VOIP+ADSL+Wireless the 7401 i have at my Parents place has been quiet good. Linksys might be owned by Cisco but dont expect Cisco performance ont he Linksys routers. I was lucky that we were able to get there Ear due to the noise we made and got local Tech support to help us with esclation for firmware upgrades. In fairness, I have read more positive things about there modems in the recent year. Also I thinkn much of there stuff is also badged as TP (at Jaycar) or Buffalo in the states.
More recently i am using a 7402VGO, which i got lots of wirless issues with (thing couldbe the number of other AP's in the area). So i got ASUS wireless router to go with the 7402VGO, the Asus with custom firmware also lets me watch IPTV over wireless on TPG.
My last few purchases for myself family and friends have been via this shop. This chap is very helpfull on the phone and does not try to sell you the most expensive modem. Instead he talked me down to the most reliable one. I should have listened to him.

A friend of mine has a netcomm and it has a simple CD that makes setup very easy. But I have also had friends with Netcomms that tend to want to reset and lose all there settings now and then.
As Robin advised dont go with the USB models.
