Well, since you only need about 15 secs to claim from a faucet, any faucet reward from 300 satoshis onwards is already reasonable and fine.
If you calculate, when you 'faucet' for 1 hour straight, ( faucet avg reward of 400 satoshis ) , you would get about 400 X 4 X 60 = 96000, which is close to 100000 satoshis, so if you 'faucet' 3 hours every day for a week, you can easily get 0.02 BTC!
There aren't many faucets out there with rewards more than 1000 satoshis, so if you just claim from them, you might not be able to claim continuously, so I think faucet rewards of 300 satoshis min is okay.
More of such faucets can be found here, :
FaucetBox FaucetsFor me, I do not use faucet that frequently, but when I do, I'll run through the list of faucets more than 300 satoshis per claim and get about 30000 satoshis.
