Dear Listers: We're looking to replace our old, beat up wooden sifting screens, preferably with plastic-framed screens. Forestry Suppliers sells a single version (http://www.forestry-suppliers.com/product_pages/View_Catalog_Page.asp?m i=3756# <http://www.forestry-suppliers.com/product_pages/View_Catalog_Page.asp?m i=3756> ), and a Google search revealed Focus Design (http://www.focusdesign.org/catalog.htm). Does anyone have experience with either of these vendors' products that they're willing to share? Are there other products out there? Thanks in advance, and happy aloha Friday - ~liz Liz Clevenger, M.A. Archaeological Collections Specialist Presidio Archaeology Lab The Presidio Trust www.presidio.gov/history/archaeology (415) 561-ARCH
