What are they dishing out now? Back in the day (mid 2000s) it seemed DLink was their standard offering.
Though they've supposedly lifted their game a bit their ADSL modems that I owned at least were pretty woeful. I had a 4-port Wifi (B) job which was outperformed by probably 10% by a Belkin which in turn was outdone by Netgear. Additional to that the earlier mentioned ones died in the arse if I had torrents going at even 30% saturation of my possible bandwidth.
Netgear is good re price vs features. Some ISPs use them as standard though generally lower end models.
I've had a bit to do with NBN and TransACT connections around here - Netgear seems a popular offering and speed issues I've encountered have been more in the infrastructure itself rather than local issues.
A big component of the price these days is the Wifi side - you'll pay a bunch more for something that does ac vs n
