The best I found in 5 minutes of looking.
One of the common issues that any traveler needs to address is exchanging money from his home country for the local currency. I think most people that go through this procedure basically accept in advance that they will be ripped off, and just take that loss as part of the cost of their vacation.
While it is true that there is a high chance of losing money during such transactions, a very little bit of effort can save you a drop of money, and might at least make you feel as if you are not a complete freier (for an explanation of that Israeli slang term, see this post from my comedian friend Benji Lovitt).
