I've never bought from Craigslist. Do they have buyer protection?
I wish I could help you with your region issues Oreo. I've heard stories about Craigslist, and usually they are never good, so I'd be wary.
I bit the bullet and bought mine retail, but that almost turned into a failure because of the system's failure rate, and I kind of got swindled. They sold me a display model that barely worked, but thanks to the powers that be, a 2-year warranty came with it. So when it failed (almost exactly a year to the date I bought it), I got a free replacement.
