There is nothing wrong with buying a bike of craigslist. Not sure how that's a rule? It's pretty much the best place to buy a use vehicle if you don't want to get raked over the coals at dealers who are just as inattentive as previous owners. The biggest thing when buying used off CL is learn what to look for as far as inspection goes. Do some research on the model you're going to see, common issues, etc. If you have a bad gut feeling, walk away, there's always another fish too.
Glad you got it sorted out, but I wouldn't immediately discount buying vehicles on CL because you had to put some wrench time in.
