I won't say that I've been burned badly re-selling rare gear. If you buy smart, and know that it is not a hot item, and are willing to wait and wear down the seller when you buy, you won't lose too much when you sell. However, you'll be on the other end then, the one being worn down by perspective buyers. Sometimes it has been worth the effort.......sometimes it hasn't. YMMV.
