Don't buy a D-Link! I wouldn't recommend them to anyone, nor Belkin.
If you are going to get a router buy one from Netgear. If you can afford it make sure you buy the wireless-N router from them (if you are using it wirelessly) or if you are plugging in your PS3 then make sure your the router has gigabit ethernet ports on that back.
(I properly recommend Netgear for any networking)
(Also, if you are plugging into your router make sure you buy either Cat5e cabling or Cat6 cabling (my preference))
