[TriEmbed] OSH Stencil notes

[Brian]

Joining this conversation a bit late, but having ordered stencils in a 
variety of materials from a variety of vendors, here are my three cents:

- OSH Stencils' kapton (polyimide) stencils are the least pleasing to 
use, IMNSHO.  They are very flimsy and feel quite fragile.

- For flexible-substrate stencils, I've had better experiences with 
mylar stencils from Pololu.  They're a bit more expensive, but I'd say 
it's worth the extra expense to have a sturdier material.

- OSH appears to offer stainless steel at a very competitive price; I've 
only ever ordered stainless steel from Stencils Unlimited.  Stainless is 
definitely the best stencil to use, in no small part because it is flat 
and rigid.  I think the premium for metal stencils is well worth it, 
especially for smaller designs of which you plan to build many.

IANAL, YMMV, OMG, WTF, BBQ!
