Tech journal or similar

I've looked on ebay and amazon.com and cannot locate any tech journals/manuals for sale. Yes I've downloaded the online tech journal from TFXART, it's AWESOME, but I'm looking for the same thing (or similar) in a book. I know Realm Press no longer publishes any BSG books so I know it's out of print. Can anyone help me out and point me in a positive direction? Price is somewhat of an issue, married with 2 kids, house, 2 cars, you know how it goes with bills and all that jazz. Thanks to any who can point me in a good direction.
