Looking for a 5" Monitor under $400
 

I'm in search of an appropriate monitor to use with a new Sony RX10 MarkII. What's the best current option that has decent color accuracy? Budget is under $400 as this is a remote camera package I'm leaving with a client. After using the A7s for a while, I find a top-mounted monitor to be a big help in focusing and composing shots.

What's good (or perhaps adequate)? MustHD, Ikan, Lilliput, Marshall, clone brands? The Sony branded one? Thanks.
