[Hampshire] ADSL Router/Modem Recommendation sought

It seems that my old Netgear ADSL Modem/Router has given up the ghost.
After a number of years service, with only the occasional need to be
re-started, for the last day it seems unable to keep going for more
than a couple of hours.

My current router is http://kbserver.netgear.com/products/DM602.asp

I would like something similar that is cheap and reliable. Any
suggestions of things to look at of what to avoid would be
appreciated.

Thanks!
