Cryptsy is up there but you are right CoinMKT is US based and has USD working with a US bank. They also have a very clean website. They just need better marketing because I never heard of them. Atomic-Trade is also in US and apparears to have a US bank relationship. Another one I never heard of them so they need to hire some marketing people. Unfortunately I can no longer edit my post.
