Here's another version of D-Link similar to the link above, but cheaper. Same great quality though:
D-Link DI-524 IEEE 802.11b/g, 802.3 Wireless Router up to 54Mbps Data Rates 1x10/100M WAN; 4x10/100M LAN
That Linksys one is pretty good too but higher priced. I would say it's worth it because it's made by Cisco and have very good security features. The dipole antenna makes it feel so strong and extend the wireless distance. Don't know exact distance though but looks nice. It is bigger than the D-Link router, but it has nice stands on the four corners of the router to relieve the heat from the bottom.
