If you don't locate what you're looking for trying Insweb, try another internet service such as esurance.  Esurance not only gives a comparison of New Jersey auto insurance rates, but it also has a wealth of information about buying car insurance.  If you still aren't happy, the next step is to pick up the telephone and call major insurance companies.  Most states such as New Jersey have offices from the major insurance providers, like State Farm and Allstate.  You can also try national companies like Geico.
