I was going to start a new thread until I seen this one.
For my birthday last month I got a Merkur long handle safety razor.
I have to say that it is the best shave I've ever had. I lather up with the old mug that was my grandfather's and a new badger brush.
I am a head-shaver as well. I've shaved the dome once not without incident when I first got the razor. I did not realize I had scalped myself in two areas until I went to rinse my head and I looked down and found a sink full of red.

I made the switch after calculating how much I was spending one machIII's over a month.
