For manual paste work, I honestly settled on JLCPCB frame-less stencils and cut them a bit to fit in my Neoden manual stencil machine. I've been happy with the etched stencils from JLCPCB, but be sure to get file confirmation so they get everything right if you need anything special.
The Euro Circuits stencil machine/system looks great, I may look into that, but the boards have to be made for the system to work right.
