Garage door opened advice needed for least expensive and best also ???

For security reasons I need to buy and install ( it is already wired from the old one that broke a long time ago), but I need to buy an elec. garage door opener for security but also I have very little money, so what would you suggest I do ? If I have to pay $200 I will, but thought I'd ask you first as I am living on pennies.Garage door opened advice needed for least expensive and best also ???
I always think of Sears for garage door openers. If a home improvement store is nearby you can comparison shop in one day.





Actually check out the websites.
