If you are not needing to cover larger distances or don't have a wireless device capable of working on an 802.11 N rated/compliant router, just using it within the home essentially, then you quite likely will be quite happy with a router meeting the 802.11 b/g standards. That will save you quite a bit of money, in that the N rated routers are more expensive. In reality the N rated aren't really significantly stronger or faster, the ads are more hype to get the extra funding.
So with that observation of experience and readings, my personal choice is a Linksys Router.... Not saying Belkin or D-Link or others are not any good, just that most testings I have seen tend to rate the Linksys as the most reliable and top of the tests. Remember, Google is your friend and you can do some research on routers, go to sites like ZD Net and others that do testings/ratings and get a feel for which router you might want to use. Just be sure you set up the security features of the wireless router so your WiFi signal is not being picked up by neighbors or drive by crooks looking for open networks to get into so they can snoop/steal and you likely will be pretty happy with whatever router you decide on. And, yes, finances does tend to be an important part of the choice equation for most of us but should not be the only consideration.
I currently use the router provided by my fiber optic DSL supplier, AT&T.... a U-Verse wireless router. After some trial and error periods on channel choice to use so I didn't get interference from other devices in the neighborhood, it has been performing quite satisfactorily.... but if I go back to cable, my Linksys router comes back off the shelf.....
