> These days it's hard to tell

Is it really? I go to my "local" second-hand marketplace and I see countless of listings for the new Valve Controller. I think it's fair to say most of those aren't "Ops, I made a purchase and I can't return it" but most likely being scalpers. No doubt, some of them are fake as well, but regardless, tends to be fairly easy to see when things are being scalped or if it's actually just high demand, if it's the latter, you don't see tons of second-hand listings the day after it opened.
