...if it really is fully reconditioned, # 2 is probably your best bet. My definition of "fully reconditioned" includes a lot of work hours and parts input.
It's pretty hard to assign a value to a Raleigh 3 speed without a hands on mechanical assessment. And you really haven't said what it would take to make # 3 rideable.

That said, I would carefully inspect a "fully reconditioned" bike that old, before investing money you could use on your current ride.
