Cheaper Insurance

The insurer recommended by Irena quoted me €270 for 90 days.

Visahouse.com quoted me €105.
Goingrus.com quoted me €90.
Travelrussia.su quoted me €60. (Based on the website address, I doubt that site will work.)

Has anyone successfully used these less expensive insurers? Спасибо

PS I am buying this insurance only because my Russian visa requires it; I don’t plan to use it for medical expenses.

Thank you. However, I decided to just use my US passport. That visa process is much easier and cheaper than the EU one!
