Marketplace - Who do you trust?

[Lamont Marable]

I was browsing over at the marketplace and I felt like I was in a foreign country walking down a local market with hundreds of people trying to sell me something.  Ad after Ad after AD!  I wanted to say "Back off!  I got mace!"  It's there for that reason but....who can you trust?  How do you breakdown the good, the bad and the "he must think I'm a fool!"  Thanks BP!
