I used 6AWG wire in 3/4" conduit to a surface mounted NEMA 14-50 receptacle. This is attached to a 50A breaker. The EVSE I went with is the JuiceBox 32A :

$500 (shipped) for the 32A plug version. I like that it is wireless and tracks my KW usage. It is portable for the most part in that it can be un-racked from the wall. I have not had any issues with it.
Be aware, you may qualify for a federal tax credit for installation.
