I'm sure you could buy everything you need to make your own stencils in-house for way less than 200K - lasercut or photochemical etch. If you have someone local with a typesetter of photoplotter , photoetch should be really cheap to set up. I've also

Just been quoted GBP500 for 5kg (2.7L) of Galden LS-230. Don;t know if the lower temp non-leadfree stuff is cheaper If anyone in the UK has a small qty they'd sell me for experimentation, (e.g. old non-leadfree stuff they no longer use) please get in
