I use the Gillette Fusion Proglide Power Styler.
The beard trimmer attachment is great for keeping my goatee nice & neat, and the razor blades do an excellent job of clearing up the rest. Those blades last me ages too, so I find them good value for money. I also use the Gillette Proglide shaving gel and I finish off with Bulldog After Shave Balm. I'm lucky to be able to get away with shaving with the grain (which is better for my skin) because my hairs are blond.
I wouldn't recommend using the cheapo razors: they tend to cut your face, don't last five minutes, and turn out to be a false economy because in many cases you have to replace them much more frequently than the more expensive brands so you could wind up spending more.
