Does anyone know of a crawler similar to SEOmoz's RogerBot?

As you probably know SEOmoz had some hosting and server issues recently, and this came at a terrible time for me... We are in the middle of battling some duplicate content and crawl errors and need to get a fresh crawl of some sites to test things out before we are hit with the big one?

Before I get a million thumbs downs- I love and will continue to use SEOmoz, just need something to get me through this week ( or until Roger is back! )!

There are a bunch to choose from, but here's a list of some freebies that pack a big punch:
