Dude, do you want an electric trimmer/shaver? I'd rather suggest not to go for a cheap local electric shaver atleast, you don't want those blades coming in close contact with your skin. Getting a local chinese trimmer is alright though, but NOT a shaver. If you're looking for an electric shaver, then Philips would be my recommendation.
On the other hand, if you're looking for a razor blade shaver, like everyone else is suggesting, I'd suggest you go for the Gillette Fusion, it's MUCH better than the Mach 3, it comes with 5 blades and a 6th blade for the sideburns, which is on the back. In addition, the Fusion Power is battery powered and emits "micropulses" that are claimed to increase razor glide.
