I have a Netgear WNDR 3400 N600 which I got for $80 almost a year ago and I have been very pleased with it. It is a/b/g/n dual band 2.4GHz/5GHz with a USB storage device port which allows me to share my 1.5TB external hard drive with every device on the network without requiring a PC "server" to be on all the time.
While this device may be overkill for a studio apartment, the 5GHz band is nice option for small spaces because of the higher transfer speed and less interference.
Personally, I want my next router to be Gigabit Ethernet and dlna certified.
