Beard trimmer. Haven't been clean shaven for at least five years now. Take the guard off for my neck line - it's not perfectly smooth but good enough for me. The rest is done with guard on and the trim length varies depending on my mood but never less than 3mm.
Prior to that though, it was always a wet shave. Basic razors about every 3 days. Luckily not in a job where clean shaven was a necessity.
