I am down for used. I don't trust eBay and nobody has anything on Craigslist really around me. I do look at gear trade frequently and that's where the contact pros are but the only malavita's they have are EST.
I got 2012 Contact Pros last year on geartrade for $125. Unfortunately I had to sell them when I downsized my boots 1.5 sizes. I sold them for $100. Too bad I don't still have em for you.
But still, I'd go for the 390 Boss if they're 2011 or newer, used or new. They're great bindings at a nearly unbeatable price!
