Garage door openers

[Beyer]

I need an opener for my 2-car, aluminum, garage door.
Is 1/2 HP enough, or should I spend the extra $40 for 3/4 HP?
Craftsman OK?

I install D.O.`s for Home Depot, I like Genie personally.. Easy to install. Work well.
Chamberlain is cheap but also good as well.. As long as your springs are good on your door, you will get by just fine with a 1/2 horse.

The more HP the better - with anything!
