I use a Gilette Mach 3 for my head, Wilkinson sword quatro for everywhere else but I am asking Santa for on of these for Xmas, they have been raved about, not cheap in the short term but compared to buying new blades, shave gel, cocoa butter and ingrown hair stuff it will pay for itself in the long run. http://www.sospecial.co.uk/productdetailstten.php?prodid=1312
Hotwax... thats the kind of wax that you spread on and wait a few mins for it to harden a little and then grab it by the corner and rip it up. Lasts 2-3 weeks but the smoothness is incomparible and there is now regrowth itch.
