Guys...
I found the generic equivalent: its medical bracing/splint material. I got a 12" x 3.75" section for $2.10, locally (rolled gently). If that's enough width/length-wise, its a good buy. But it does come in longer rolls medically, and bigger pieces commercially...
Michaels craft stores (among other places) also carry it in sheets: (had to use Google to find it, 'cause Michaels search engine is CR*P)

Its proper name (to google-search) is: Activa Activ-Wire Mesh.
One seller on eBay has 12" x 24" pieces (folded) for just over $6.99 & shipping, Michaels' price is $4.99 (Cdn). It does come in various grades, measured by the mesh openings.
HobbyLobby,
www.Sandtastik.com and apparently even Walmart has it as well, and in the following sizes/grades: 1/4"x1/8", 1/8"x1/16", & 1/4"x1/8" rolls at 2'x10'.
If you want to look about, its generic name is 'expanded aluminum mesh'. Use this name if you ask at a metal shop.
Hope that helps you out,
WhiteWolf
