[QUOTE=filmecyan] I saw the headblade site, but they sold a cartridge razor that looks like a vacuum,

I saw that too, $75.00!!! I used to use a regular cartridge razor to shave my head and it did do a fine job. I just think the headblade is easier. It basically clips to your middle finger and it seems easier to control, I have less missed spots that i have to go over again. But, I would never spend $75 to have one with wheels.
