If you are looking for simultaneous, this one is great - http://www.newegg.com/Product/Product.aspx?Item=N82E16833124388&cm_re=wireless_n_router-_-33-124-388-_-Product
Also, here is another "n" wireless router - http://www.newegg.com/Product/Product.aspx?Item=N82E16833124344&cm_re=wireless_n_router-_-33-124-344-_-Product
Most are equipped with Ethernet ports (RJ 45) - haven't seen any with Ethernet as well as USB ports. Maybe additional technology is required to do so, thereby raising the costs.
I personally find that Linksys routers and wireless cards are great. My wireless router is 2 years old, and cards are 6 months, and 2 months respectively. The router is "g" technology whereas the cards are "g, n" technology.
