I started down that same path and had the same feelings. Up until someone broke into my car and took my BOB filled with $200.00 worth of gear. After reading Cody Lundins new book and this web page http://www.theplacewithnoname.com/blogs/klessons/index.html

I'm planning my kits to be simpler, with economical or moderately priced gear. While debating with my father about the best bug out gun, he reminded me that at the end of his tour in Vietnam he had gone through 4 various rifles, a grease gun, and several sets of boots and web gear. All for various reasons. The point being don't assume all your gear will make it to the end of the adventure.My kit may get lost, stolen, traded,ditched or destroyed before the adventure is done. My concern is that my gear would be so expensive that it would cloud my survival judgment and make me less flexible.
