There are certainly many other hosting companies out there, some of which appear cheaper, but there is a difference between low cost and good value. I have not found a hosting company that is better than sitegound
So far, I only found more expensive alternatives. Siteground provides a decent price / value ratio. I believe there might be better hosting around, but price wise definitely more expensive.
I think their pricing is in line or better than most hosting companies. The big difference is in the professionalism, outstanding customer service and ease of using their dashboard.
Just like others have said, Siteground is very good now with their customer service, tech support, dashboard. You can find cheaper but its definitely not worth the hassle. I'm staying with them.
