I use a Braun Syncro:

Works pretty well and the self-cleaning station is nice to keep it running well and maintenance hassle-free. You still have to pay upkeep on an electric thanks to the cleaning kits and foil/blade replacements but they're a lot less frequent (18 months for blade and foil, probably every 3 months at worst for the cleaning kit). You also usually get multiple parts in a single upkeep buy so your dollar spent goes further and you have to spend it less often. This particular one is nice in how the foils and blades are designed in such a way that I can go several days without shaving and still use it without it tugging on my face when I do come back and shave (most will require you to shave every other day at minimum and if it gets any longer than that you'll have to use a trimmer edge before you can hit it with the standard foil). I'm not sure if that design has carried forward to their current systems or not.
Can't speak on the electric toothbrush, I've never personally seen a good scientific justification for one (but I've never really gone looking for one, either).
