I use HTTrack which is also found at Son of Spy. It is a program to create a mirror of a website on your hard disk and you can set parameters such as how many layers deep to capture, etc. I'm on a DSL connection and it took me less than 5 seconds to capture the Silverstein site - in fact, I spent more time setting up the capture than in performing it. If a site prohibits 'bots' HTT won't work, but I've found few that do. I tend to set up my captures for late at night when I won't be slowing traffic too much on the site.
