Oggin,
The Netgear ADSL router you've identified will do the job perfectly well. At the end of the day there's very little to choose between the well known and established makes - Belkin, Netgear, 3Com, Linksys.
The layman just needs to have clear in his mind the difference between a pure router and an ADSL router. The former makes available the already received signal to other devices by means of hardwire cables or by wireless. The ADSL router does all of the above, but also acts as a 'modem' on a standard broadband line in order to receive the signals in the first instance. You can't use an ADSL router along with an existing ISP's modem or on cable systems (as in effect you'd have two modems trying to work at the same time).
Hopefully that hasn't muddied the waters any further .....
