If it's not too late, another vote for the Horseman -- I believe they are also available under the Arca name. Do remember that they do their backs in formats other than 4x5 so make sure you go for the right type.
You can also get Wista backs but, on an admittedly small sample of 3 backs, I have the impression the Horsemans are a little more robust -- I'd still get another one though.
The DaYi and Art-Panorama backs are more primitive though you can get them as multi-format (expansion) backs going up to 6x17
