I'm afraid Shapeways have recently increased their prices on WSF models. I'm now offering the WSF-P matrial option as this gives a fairly smooth finish, but does lose the sharp edges of features. Recent communications with customers suggest the White-Strong-Flexible material is more than suitable, but does need a primer-filler (Auto-shop, 'Duplicolour') paint to smooth out the 'powdery' finish. The wheels are now 'fixed' to prevent manufacture problems. My thanks to Mike Ozosky for the pictures of his pups and 1040 cow/calf combo using my models.
