I tried Dwarfpool but found a pool that lets you withdraw coin at, virtually, any limit unlike Dwarfpool which has quite a high limit for a small miner.
The pool I use is Mining Pool Hub,
http://miningpoolhub.com/Dwarfpool (For Monero): Pool Fee, 1.5%. Withdrawal Transaction Fee, 0.008 XMR (0.014 to Exchange). Minimum Withdrawal Limit, 0.1 XMR.
Mining Pool Hub (For Monero): Pool Fee, 0.9%. Withdrawal Transaction Fee, 0.015 XMR. Minimum Withdrawal Limit, 0.05 XMR.
I thought Dwarfpool was at 0.5 XMR minimum withdraw limit, some pools are - maybe they lowered it.
Mining Pool Hub has a significantly lower pool fee which more than offsets the higher transaction fee.
