I use a Remington Ti Microflex - about 4 years old, got it at Kohls. I've replaced the heads once, and probably need to again soon, but it works very well.
usually it takes 3 weeks or so to get used to a razor. part of it is that the hair will start growing in a way that makes the razor pull less, then not at all. also, it takes about that long for the blades to wear down to match the foil. after a month you should be smooth. that's been my experience with all of my electric razors. I do use a Mach 3 if I haven't shaved in a week though, just much easier to do it in the shower in the running water... I just rough it out, then take care of the details once I'm out and in front of a mirror.
