Geoff,
I have a Girard 2000 electric awning and it has been trouble free for 10 years. If you want an electric awning, I would recommend a Girard. It has a remote control that I keep in my car glove box and when it is raining we hit the remote control and open the awning and drive the car under the awning so we don't get wet. It's great!
One disadvantage to a Girard is they can not take as much wind as a manual awning because the support arms are different. Either way you go you'll love your new awning.
