Httrack is good as many people have said, but depending on how you wish to use it - Chrome's save as complete HTMLi s pretty good as well. What's nice about it is that if you're just saving one or two pages,it will change all the relative paths of images to a folder making the image/javascript/external files paths have a different footprint than the original site (e.g., /name-of-saved-file/images/file.jpg instead of the original /images/file.jpg).
