http://faucetsystem.com/ looks like they have a list of sites that use their faucet. I don't know any other legitimate faucet micro-transaction hosts. I didn't dig to deep. But there's probably more out there.
Maybe check reddit, and the other Bitcoin forums.

& I might be stunted mentally or something, but there's a soothing nostalgic enjoyment I get from slapping a few faucets. Reminds me of the days where the faucets would deposit way faster due to the mempool avg size/fee difference from back then ad now.

On another note, What type of AltCoin faucets have been created these days?
