In general it would be great if the coin is listed on any exchange, if it was not premined, has at least one working faucet, and doesn't have more than 3 zeros after the decimal point when compared to the USD.
Here's a small snap shot in alpha order of alts I like:
Dogecoin, Feathercoin, Goldcoin, Infinitecoin, Litecoin, Mooncoin, Peercoin, Worldcoin, Ybcoin
Is that a joke? I don't want to sound arrogant but you condition about zeros after decimal point and acctually the whole proposal is quite awkward. If you want to gather some info maybe just read in http://bitcoinmagazine.com/ about alt currencies...
