i bought an a-liner decided i wanted a 13f
scamp
my formula
do a 3 or 4 state search craigslist anything you can dream up do it daily you will get to the poiint almost hourly
before you land a seller have your rig ready, have you limit set and be able to get it quickly, after talking to your seller be prepared to send a deposit, you will be able to tell if he is honest and not setting you up!
be ready to roll with in 24 hours if its a
scamp or one of the others buyers will be lined up!
good luck in your search
