Initially I was one who placed a lot of credence to brokers reports whom I thought to be independant...I learnt a lot from that mistake, when I now see a glowing report I now think how many newbies thinking they are doing their own due diligence in reading them are going to get sucked in.
I would be careful not to point out any brokers in particular,in general used care salesmen seem quite respectable to me now in comparison.
