His history and reputation is all you need. If you can't access your funds, I highly recommend Dave. He worked wonders for me and others. He has had so many opportunities to just take funds and run, killing his reputation for a quick payday but each and every time he comes through and gets the funds out of the locked wallet, takes his cut and provides you back the password.
Whatever route you take, good luck with your locked funds, it's a tough spot to be in.
