<DIV><BR></DIV>Tom, the most efficient method for me has been to call a buddy
with a laser and have him bust them out for me. There are several I have
worked with, but prices have gone up so much as of late, I now do most
prototyping by hand again. <BR> <BR>As for fuses, they are pretty crude
for a reason. And the big watchout is that there are good profiles out there,
and then there is mass marketed garbage. <BR> <BR>I'll shoot you some
stuff off list that I think you'll enjoy : )<BR> <BR><BR><BR>> Date:
