plastic stencils are cheap, I get mine from http://www.smtstencil.co.uk/ No need for any machinery, just tape it to the board, then squeegee the paste using a credit card. Works fine, for low volume, and is easily capable of 0.5mm pitch. More of a concern, if issuing kits of parts, is how to deliver fine-pitch QFPs with their legs intact. The best way to package them for shipping may well be to attach them to a PCB with some kind of melted metal... (This is probably my first post here.
