Big pulls!! 308 for 6 bench is nice work too. Rubbish working, eating and sleeping seems to agree with you.
I'd buy your book. Ever thought of self publishing? There's sites that handle that stuff now. Only print one when you sell one, that kind of thing. Not too much upfront and while the back end a is a little lower too, at least it is published, and it's not unheard of to have a self published book get picked up by a real publisher if there is demand or proof of sales.
I have dabbled in this with a few of my writings. I haven't pulled the trigger on any of my projects (lack of time and gumption), but thought I'd point this out as something to look into.
