How to best save a website for a portfolio

I designed/coded some websites that I know are being taken off the web. Before they are taken down, I obviously want to somehow save my work for my portfolio.

What is the best way you recommend saving these pages?

.pdfs?

if you have access to them, use an ftp client to simply 'download' or copy all the files and folders onto your pc. that way, you can just put them back up when you lose that webspace and you can put them back sometime in the future when you find another host.
