Tool to mass check PR?

I need a tool that can check PR (10s of 1000s URLs) and supports proxies. SB can do that I know but I don't need all its other functions. Can be a paid soft, it doesn't matter.

Thanks for any suggestions.

You should just pick up scrapebox, I'm sure you'll find it's other functionality useful in the future. And I don't think you are going to find a standalone PR checking program that much cheaper than scrapebox.
