Getting liability insurance

I am a brand new nurse and want to know where do I go to get liability insurance. Do you guys have advice?
The two companies that get mentioned most often are NSO (Professional Liability Insurance for nurses, nursing medical malpractice.) and Marsh (Professional Liability Insurance - Proliability). Some member here have mentioned in the past that they have coverage as a rider on their homeowner's insurance, but I have no idea how that would work -- I am more comfortable dealing with an insurance company that specializes in covering nurses.
