Depending upon what you are needing in benefit or duration on the life insurance just make sure the premiums are fixed and level for the entire duration you are looking for. In 2015 the carriers we are mostly finding doing a great job at low cost for term life are Lincoln, Transamerica, Ameritas, Banner, Ohio National, Protective, and Prudential.
As for Disability Insurance, it depends on the definitions of disability that you want and the state that you live in as to what products are available for sale there. In most states today the carriers with the best definition of disability are from MetLife, Standard, Ameritas, Principal, Guardian, Mass Mutual, and Ohio National. Now keep in mind that all of these will change premiums based on age, gender, medical specialty, and state of residency so make sure you work with an agent that is very familiar with this process.
