Probably my favorite stencils right now are Alexey by Thirstype, and Robocop by Apollo 26.

Er, I mean Defcon 3.

Rian Hughes' Paralucent Stencil is one of my favourites. And the stencil weight of Granite by Gareth Hague has some wonderful details in it.

Le Corbusier by Lineto.

A few more, at 'Stencil Revolution'..

( 'Gunplay', by Ray Larabie, maybe.. Just in case you are seeking a free one.. )

Funny stuff, David. I was just going to link to that site. One of my favourite sites.
