I want to say that I am mining DGC from the beginning and i have tried almost all of these pools, but the best for me is http://crypto-coins.de:8907/static/ (I am located in EU). The reward was great (even more than i expected ). Its a pity that hash rate is only ~24MH/s. But after giving a try to that server located in France i have decided to get back to schnebi's pool. I hope more EU miners will come :-)
On other pools i have weird payouts, sometimes i did not get paid for blocks, or reward was 50% lower then was from block found 5 minuts ago, even the fact i was still mining. It happend to me 2 times that my DGC address just dissapeared from payout list after receiving a payment few minutes ago and still mining.
Last thing i want to say is that you should buy those grenaders http://www.bitgrenade.net/?coin_display=6
I think the pool is running really smooth now, after a few problems yesterday. The Server could easily handle 10x of the hash rate it has at the moment
