Hmmm, i followed the link given above and now i know what you need.
I suggest: Do it the Amiga way:
Create one! Or you can modify the one you already have!
All you need is a Hacksaw (a saw for metals) and some sandpaper (also known as garnet paper) or a file (not a file in a computer, a FILE - those things you can "scratch" metal surfaces. Like the ones women carry to "scratch" their nails all the time and drive you mad... The only difference is that this kind of file is more useful than the one women carry ...)
Well, that's the amiga way. If you can't buy it, do it yourself :-P
