Hey, I am one for the Wilkinson Swords that you can get at Walmart dirt cheap!!! They shave beautifully and last for several shaves 4+, just posted somewhere about it earlier today I think! They have a nice cut and work very well on my super coarse hair.
I have tried the Personnas, and they are wonderful as are the Derbys, but I don't find either to be a superior shaver to the Wilkinson for my face!
I have not had good luck with the feathers! They are very sharp and give an unbelievable shave, but I can't use one more than twice and I end up with a touch more razor burn! They ARE that SHARP!
YMMV, but for $1.75 for the Wilkinsons at Walmart, it can't hurt to try them!
