New razors are nice.
But wouldn't it be cool to say that you fixed a problem razor that you went from having no idea what was going on with it to feeling accomplished in fixing it when you go to shave with it and its awesome. I've not had a serious problem like this myself but if I did then I would try to fix it before I sent it out unless it was really really expensive or a one of a kind deal.
But of course new razors are nice....
