QMX will soon be releasing for pre-order a very nice River Tam Maquette. This is a limited release of just 1,500. The statue has exquisite details of the costume and props from the scene in Serenity that inspired it, and is cast in polystone resin and hand-painted.
The base is also highly detailed and sculpted.
River Tam will soon be available for preorder for US$69.95 from QMX
