I've used Linksys routers for years and am impressed with them. I have heard enough anecdotal bad stories about Belkin routers that I would personally never buy one, but those are just anecdotes. My favourite is the Linksys WRT54G -- its current incarnation is 45 EUR on [broken link removed] (who I have also used many times and never had a problem. Elara seem good too). If you want a cheaper router, the equivalent Belkin wireless router with 4-port switch is 29 EUR on komplett. (I have no connection with any of these companies).
House construction can affect the reach of your wireless network. If you run into problems, you can run cabling and install additional wireless access points. Or, much simpler, you can run a network extender over your house's electric cabling, providing an ethernet connection in another room either for plugging in a PC directly, or adding a wireless access point.
