Taming Amazon discussion

I've recently run across a website, OnlineBookReviews.org and wondered if anyone has worked with them to get reviews. What was your opinion of their service? How many reviews did you get? How much did it cost?
Thanks,
Jim

Did you use OBR.org? I looked it over but never did it. They send a lot of emails. Would be interested to hear your thoughts if you did try it out though.
