hey guys looking to buy a new router. I can get the 6th gen AirPort Extreme for 60 dollars or the Asus Tm-1900 (which seems like it's an Asus rt-ac68u rebranded) for a 25 dollar deposit. Is there a big difference between the two? I live in a medium sized apartment in NYC. Have a couple rMBP's, Apple TV(currently AirPlay is a little laggy), and two printers. One laser and one large inkjet for photos. I would love to be able to connect both printers but it seems like the AirPort Extreme only has one USB port and the Asus has two. But I need to connect an external hd to the router so I can use time machine to make back ups. Could I do this on the Asus or is it an AirPort Extreme thing only? Which do you guys think is better?
