The ones from LePrevo are good. The only thing that I found difficult to get were long stem eyelets, strangely that was solved at my local haberdashery where they sell them (god knows why, but it's handy). I also use eyelets with considerably larger internal diameter (upto 21mm internal), if you ever go up to larger sizes don't mess around with cheap kit, buy C.S. Osborne dies and eyelets, in the long run it'll save you time and money.
