You have to gamble and take risks on some things, bad pictures and the unknown. Yes you can loose small amounts of money, which is always disappointing. Gambles for small sums of money do work out very well sometimes. What I find extremely upsetting, is paying good money only to find when you want to sell it, you have paid 3 times what you get back. Also if you only buy what is illustrated in the most popular of books, you will not gain.
