have had the best luck w/a mach111, and am not surised to learn they dull easily - i get about 5-7 shaves out of mine - other than the mach111, a trac-11 works ok, as good as the competition anyway - go thru stages, right now on a manual razor stage, but when in electric mode, use a braun which works ok, but not as close as the mach111 - have gotten a straight razor shave a few times at a barbershop in a hotel in new orleans, and they are hard to beat for comfort, closeness, etc - but expensive, $8 i think, not counting tip, $10 in all - pretty high for a shave imho
