I just did the math while looking at a $100 SE razor that uses DE blades (I'm new and I can't spend 30 minutes every morning shaving, so I was comparing quick and dirties).
I get a full month out of fusion blades if I am doing a daily clean shave as long as I take ten seconds to clean and dry the blade after use. These run me $3.25 a pop.
I just got into DE shaving, and am using an MTO until my AS-D2 gets here. It looks like feathers last six shaves(ish) and I can get them for $.30 a pop.
Thats 10.7¢ a shave for top notch carts vs 5¢ a shave for top notch DE razors. When you look at it that way, with cheaper production costs for the DE (it's a set design, looks mostly animated, not much advertising, and it's done predominately overseas), the American made, "cutting edge technology" and complicated carts aren't such a bad deal.
For me, simply not having to repeatedly bang the razor on the edge of the sink to dislodge the stubble funk from underneath the blade(s) after each swipe makes the DE the obvious better choice.
