Probably the best way to mine without having your own setup at home.
Have been a customer for about 5 years. They offer a fair price for hardware, very reasonable hosting fees, and excellent and responsive customer service. Power outages and repairs are just a part of this business, but compass is prompt to respond and fairly compensates you for downtime. Their interface is easy to use and they have real U.S. based humans providing assistance. Most recently, I updated one of my older rigs. Their sales staff was extremely helpful, got me a great price on a new rig that took advantage of a sales tax shelter for data centers, a fair credit for my retiring rig, and a good deal on hosting, and the new rig was up and hashing in about 1 day.
