...secondart..really cool site that lets collectors like you and me buy n sell high quality art! it's in the uk and i don't know of a north american version. dealing in art involves a lot of commissions from all sides, which at the end of the day hits the art buyer. it's nice to be able to cut out the middleman -- hoping this model does that to a degree. only fee is listing charge of 40 pounds. not bad..
