I think it is a good idea but I have a suggestion. Instead of writing it as a book that teaches you how to beat the SNG, I'd recommend a book that teaches NL Holdem to people that may have seen it played on TV, and to limit holdem players that want to try their hand at no-limit, BUT the book uses SNGs as an inexpensive training ground.

Once someone can consistantly beat these SNGs they would have a well rounded skill set (playing when stacks are deep on 1st level, to playing a short stack or a big stack, and playing short handed or heads-up, etc).

This would give you a MUCH bigger market. Not a book on SNGs, but a NL Holdem book that uses SNGs as a training tool!
