Get the cheapest one. Belkin N150. If you can double your budget, go for the ASUS RT N13 U ver B1, get it and download torrents on that instad of your laptop.
Thers a nice buffalo router that can cover till about the road ahead of your house, another something youd wanna check is the ability to load a custom firmware on it for better tweaking.
+1 for asus rt n13u with usb - you can plug in ur hdd and download without having your pc on. If downloading is a must then i would suggest you to go with a router that has a usb port
Both should be good. I have 2 friends using belkin n150 and one friend using netgeaer and they all are satisfied. If you want more range get n300 and not n150.
