I've just started with hashie (https://hashie.co/t?p=11245&v=3e1) and the site is nicely designed and simple to use.  I asked a couple of questions to support before buying my first miner (after starting out with a free one for a day) and they were responsive.  Overall after seeing all of the other cloud miners out there hashie seemed the best to me to try out cloud mining and to do something with my bitcoins other than check the balance in my wallet or gamble them away ;-)
