Without reading the last 33 pages, whats wrong with a Mach 3?
Nothing, if it works for you then the answer is keep using it.
I'd rather pay a bit more for something & then have very little outlay afterwards.....that was the plan before I started buying packs of blades, shaving soaps & balms, still it gives a better shave with no irritation & I feel better for taking a bit more time to do it.
Straight shaving is the way to go though
