I am clueless when it comes to routers, modems, and the likes. I was interested in getting an Airport Extreme or Express, but then I noticed the prices. When going over to my local department store, they have cheap routers such as Netgear for about $30-40. What are the major spec differences between these two products? Is dishing out an additional $100+ worth it? What other products will I need to get to have wi-fi working in my new apartment. In my old apartment, my roommate had a router and modem he rented from Comcast. Do I need a modem as well? Sorry I'm so clueless, so if someone could help, that'd be excellent. Please feel free to express your opinion on which one I should get, thanks.
