I also tried Remington's Epilator after hearing big raves for it. I actually tried it on my armpits (the pain was horrible at first, but you can now buy numbing sprays to help) and I must say that my hair did not grow back for three weeks, however, I also tried it on my arms, but unfortunately for some reason it did not work - it did not remove hair from the root and only left me with stubble.
As for wax, the best that I have tried is ceripil (blue wax) which is for professional use only, however I was able to get my hands on some but only use it for facial purposes.
As far as razors go, I prefer men's razors which give me a better shave - I like the Gillete Mach one and even prefer it over the Venus which was made for women.
