eBAY is fine, there are lots of great razors to be had at very reasonable costs, provided you know what to look for and are prepared that the razors you buy, will have to be restored to various degrees of cost. You can get some normally very expensive razors, for a superb price, again, if you know what you're looking for and prepared to invest additional dollars in some work for them.

If you're simply looking for a nice vintage razor, ready to roll, I agree that the Classifieds here are simply the best place to find them, you know the quality and shave ready status from the ad, and I've never gone wrong with the many razors I've purchased there. Aside from that, the vintage razors in the Classifieds are usually priced extremely reasonably. Hope this helps.
