I can understand your concerns, but I'd suggest a different tack. Buy and read the "Deep Survival" book Doug links to on the main page. One of the recurring themes that the book has was a failure to research the area being visited. I think that applies here, too. Figure out what the most common issues are, and weigh them up. To some extent it helps if you have an "acceptable criteria" when making decisions.

Mine is a simple one - I won't go anywhere where I have to be disarmed. Once past that, I've found I have plenty of choices still.
