Do they make a router that will take wireless in and out?
No, routers only come with one wifi controller.
one thing I can think of is to use a router and use it in AP Client modehttp://www.newegg.com/Product/Product.aspx?Item=N82E16833156262
and then connect another router to it.
the other thing would be to use a router that can be upgraded with DD-WRT firmware, program the wireless lan port via Virtual LAN to become a WAN port; however, this will still only give you LAN ports to connect to and no wifi.
