I've heard about this for years but never read it. A month or so ago the Stakeout Squad was mentioned in a podcast or two I was listening to (maybe Scott Reitz's podcast) so I went looking for the book. I didn't know it was out of print but some digging turned up a revised and expanded version available from Paul Kirchner. He retained the rights when Paladin Press went under and then he went back through his notes and interviews to add more to the book.
He's self publishing it and selling them on Gunbroker
I ordered a copy on a Friday last month and had it in my hand the following Tuesday. Now if I would just make the time to read it...
