I usually just head down to the local native tribe and get them to transfer my work into some bead-work or quilt.

pics or it didn't happen.  seriously though, that would be awesome.  probably pixelated though.

The hard back books you can get printed off the internet look good.  Not the most creative but if the works good this is a decent option.  

Curtkram, the problem is not really about the pixelation but some of them insist so much on adding tassels everywhere.
 

I use Lulu, but my last run of portfolios had some trim marks visible on a couple pages. I will probably give Blurb a shot next time I want a hard-copy. 

For most interviews, I have switched to showing work on a 10" nexus tablet - the graphic quality is amazing, and at $400, I only have to revise my portfolio like 7 times before it pays for itself.... 

Blurb is fantastic and if you're using their InDesign plug in, your cost per book will auto-update as you add pages and or change the paper quality... no tassel option, which is good.

I interviewed with a  tablet last time.
