No rain here.

First of all, SBI! has a 30-day unconditional money back guarantee. After 30 days the refund amount is prorated. So it is definitely risk-free.
One big difference SBI! has over many of the other "regular" or "cheaper" hosts is they provide the education you need to succeed. It's not just about "putting up a site" and then figuring out how you are going to get traffic and make money later.
It's about understanding how online marketing works, how people search the Web and discovering your best niche/topic
BEFORE you begin. SBI! walks you through an extensive process to learn and understand all this before you even begin creating your site. That is the big difference.
Could you get the education online for free? Sure you could but you'd have to know where to go and who to trust. SBI! provides all the tools in all one place... including a site builder.
As I say a lot. It is not for everyone. The only way to know is to try it out for yourself. Many people succeed with SBI! and many people fail. I think the difference is dedication, commitment and how much you enjoy this process.
