That's the one I use and just save all PDF files I need. Then I use Foxit Reader to view them. That's a great program, it just does what I need it to do without the bloat. Only thing is that its printing capability is not quite as good as Adobe in terms of speed, but I'll trade a few seconds for a more streamlined program.
