I enjoy shaving with my DE razor, but it does take quite some time as I have to shave my entire head and face, except goatee area. Blades are only 10ยข each, so I only use for one shave.
My razor of choice is a 1954 Super Speed. And yes, it's all about learning the angle. What I really l like about the DE is I can make multiple passes for a super smooth shave and never get any irritation.
One per shave? Wow. I guess I shouldn't feel bad using mine for 3-4 shaves.
I get a couple of shaves from each blade but I shave against the grain so it might be different for some guys. I'm using a 1912 gillette de and love it! They sell for next to nothing on ebay. I've never used the dorco razor but I heard it's good. It is plastic though so I don't know how long it will last. I never had a problem with my de and I'm a bit spoiled because nothing I've tried will give a closer shave. There might be a learning curve but not much.
