Sorry for off-topic. Just want to share "my story". One of my recent "day maker" purchases was not a camera, but book about cameras. A while ago I was reading something online about Takumar lenses, and that forum thread pointed right to Amazon's page for "The Ultimate Asahi Pentax Screw Mount Guide 1952 - 1977" claiming that it is very rare book impossible to find, or you have to be ready to pay really good price for it. I opened link and was surprised to find out that book is available for sale for $1.30 with $3.99 shipping. I purchased book and got it my mail one week after. So now I'm a happy owner of that great book..
