Open Question: Is anyone a member on Loop Net?

I was thinking about signing up at loop net. Its $40 a month to see every listing. They already show you a few listings but not all. Is it worth the monthly fee? I'm looking for a specific business to buy and supposedly loop net has 50 listings of this business available for $40 a month. I'm worried I'm gonna sign up and there not gonna be the businesses I'm interested in. Anyone have experience with Loop Net?
