Nursing Malpractice Insurance

I'm a new grad just graduated in May. I wanted to get some advice on what is the best company to go through that provides us with this insurance. I have looked into NSO. It all sounds good, but before I sign up for anything I wanted to see, what you more experienced nurses out there recommend? What have you found to be the best company to buy this insurance through? Thanks
NSO and Marsh are the two companies that get mentioned most often in these discussions, that specialize in professional liability (malpractice) coverage for nurses and other healthcare professionals. There have been members here who have posted that they have liability coverage through a rider on their homeowner's insurance, but I have no idea how that would work -- I've always preferred to do business with a company that specializes in this kind of insurance.Personally, I've had insurance with both NSO and Marsh at different times in my career -- I have no complaints about either company, but, on the other hand, fortunately (knock on wood!), I've never had to use the insurance.
