I've got a Netgear DG824M wireless modem/4 port router (dont think it's still made as it's 802.11 B wireless rather than the 'current' 802.11 G.
I've been really impressed so far, never had one problem with it. Port forwarding is a doddle, & it's been as stable as a rock.
Here's where I got mine (I would recommend them too!)
