Finding blogs with decent PR

I have been marketing a client's site recently by posting to blogs and forums on their behalf. Finding blogs on topic is not so difficult if you use Blogsearch from googlebut finding blogs with a reasonable PR to pass link juice on has not been easy until now.
Last week, I did a trawl around to see if there was any software that would make finding high PR blogs any easier and came across the free version of FastBlogFinder. This only allows you to see 50 blogs for any search term, so I have decided to upgrade to the Gold version. It is definitely worth trying the free version - download it today.
