Friends don't let friends buy from online auction houses. It takes patience, practice, and a good deal of knowledge (and, of course, luck) to get decent razors from eBay,
especially at the price you mentioned. Whereas your chances of getting a decent razor at a decent price from the classifieds here is a lot higher (there is still a risk, though).
Straight Razor Place Wiki:Books/Beginners Guide - Straight Razor Place Wiki is still the best place to start in my opinion. There is a shopping list in there as well, and basically everything you need to get started. Read it.
