The nano range is off as the seller at 28 ended up dumping it on scrap.tf after only a week. I would use the napper sale to price the nano instead. Would go 38 flat here. That would put the nano at 36-40 if I'm not mistaken, which is supported by the marketplace seller and current classified seller there.
