I use a razor most of the time, but I do use an electric on occasion when I'm in a hurry or want to touch up between razor shaves. I have a Panasonic 8103ES. It is good for my face but takes too long on my head and leaves patches. A better choice for just the head is the Philips Norelco QC5580 Headgroom. It has a lithium battery, holds a charge for an hour, is easy to clean, and provides a decent shave (as long as there is not more than 2-3 days growth). Plus, it also has a clipper attachment if you want to go with a longer buzzcut (but why would you?
An electric won't cut as close as a razor, it just can't, but the Norelco is the best I've used on my head and it is convenient for days that I am too lazy to whip out my brush, mug, soap, and razor.
