This faucet still has >400 coins... and you can get a max of just over 0.8, so it fits your bill:http://bitcoinfaucet.uo1.net/
Or... just set your rig to point to testnet pool and mine some yourself? Shouldn't take more than a few minutes, assuming you already mine Bitcoin.
P.S. Your error message doesn't seem like you're trying to access a faucet at all... "Not enough funds in the wallet to tumble" suggests you're trying to use a mixing/tumbling service?
emmm.
http://bitcoinfaucet.uo1.net/ shows that current wallet balance is 414.35778642.But i can get up to 0.08287000. ( 0.08<0.8 )
Besides i only have a pc(cpu). This does not seem to be suitable for mining.
P.S. Yes, error message comes from the tumbling service inseated of faucet.
