In answer to your questions; YES electric brushes are better than manual! Here's the good news: there's one to fit every budget!
The vibration in power brushes not only removes plaque more thoroughly, it literally breaks the cell walls open and kills the bugs. How cool is that!
My favorite is the ultrasonic, rechargeable models. They range from $30 on up. However, if it's just not fitting with your economy right now, go ahead and get the battery operated and save up for the rechargeable unit you want.
Don't forget to floss along with that toothbrushing.
