Listed below are telephone contact nos. for various Travel Insurance providers.  
I attempted to compare but found it impossible. Personally, I liked TIC because they don't use our $50,000, not pre-medical conditions up to 71, fast and convenient to obtain, no forms to complete, local and reasonable cost.  Try comparing some yourself .
