Let me leave my honest opinion. An escrow should have the capability to handle the situation if something went wrong like lost funds by his mistakes or whatever. On the other hand, trust is quite important as well. An escrow provider must have enough trust & enough financial solvency. But we have to think about the situation as well. Sometimes situation would be bad for an escrow provider as well though he do not intend to rush his trust. An escrow provider should be established financially that he shouldn't sell his soul eventually for money.
