Just to chime in here I have run into several 'questionable' ads within the last week or so. There are many good deals/sellers but also the a=holes.
I have found a few bad ads at CycleTrader as well.
Just be on your toes and do your homework/research thoroughly.
BTW I still don't have a BD yet but it ain't for lack of trying. I will pull the trigger one of these days.
Keep all the good info here coming guys.
I plan to take some vacation time this month and make a personal visit to some of the sellers and check out there bikes. I still want a 2007 Mastiff but a few 2007 K9's have got my eyes too.

P.S. Has anyone ever dealt with Dream Machines in Dallas, TX? They are always selling no less than 20 used BD and those bikes are in/out the doors quickly. Just saying.
