I am a new member, I have looked over the classifieds and was wondering what kind of razor I should buy. I have seen some razors that you can change the blades on, and others that look to have a blade that you never change. I was wanting to sharpen my own blade to save $$. Are the razors that have 1 "permanent blade" good? Last a long time, or is it better to get one that has changeable blades?

Thanks,
