Re. the Don Casey book. Your library may have it. I know mine does.
Re. survey, look at it yourselves first, then if still interested you would be crazy not to have a survey done. As has been said here earlier you will need one for insurance anyway. If there are issues that need addressing you will need to have another one after you fix them (to satisfy insurance company) unless you pay a reputable yard to repair. I believe it will be cheaper to fix yourself and then get another survey.
In my case I bought a boat that had a leaky fuel tank. This was noted in the survey so no insurance until afterI replaced it myself and then hired a surveyor just to inspect my work so it was much less than a full survey would have cost.
