We've used the plastic one.  It is okay for relatively light duty, but I'm 
not sure how it would hold up under heavy use.  A little awkward to carry 
but sets up easily and is self-supporting.  Also easy to replace the screen 
when it dies.  Also has rounded corners which is nice--doesn't trap dirt.

Subject: Screen Vendor?


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 -
