I have some links at the bottom 
here:

http://www.oion.net/plug/qnd/cel-
supplies.htm

But this page will likely be moving 
eventually once my gallery goes down for law school *fun* 
besides the fact that it's been under revision for a few years 
(maybe I'll get around to finishing it, or just pass it off to 
someone else) ^^;

(I personally used PlasTech and bought 
in massive bulk.)
