I've tried lots of electric razors and none have worked well for me so I use a Gillette mach 3 and some nivia foam (I hate the gel stuff). Like I said, I have to shave every day for work and sometimes my skin gets irritated under my chin and almost gets sort of a rash on occasion. After reading this thread, I ended up getting a merkur HD, nice brush, blades, soap, etc from Fendrihan. They shipped fast and everything was packaged well.
I was a bit afraid of cutting myself, but found it just as easy to shave with as a cartridge razor. I think it takes a bit more technique to get a close shave since there is no swivel like a cartridge razor and you have to control the angle. I didn't find it to be any closer shave than the Gillette, but maybe some more experience will improve it. That being said, the shaving soap is far better than the stuff in a can. It feels cool applying it with the brush also. My only beefs are that for some reason the Merkur HD has like a 3" handle, so I would recommend getting the long handled version. Also, when you wet the badger hair brush, it has a strong smell of... wet badger (surprise!) I've read that it wears off though, but I was actually surprised that they don't get rid of the smell when they make the brushes. The blades are ridiculously cheap compared to cartridges. I haven't done the math, but obviously the initial purchase is a few bucks, but it won't take long to pay for itself in cartridge savings.
