	Although it *is* a bit small for my app, I'd like to perhaps buy
a few of them anyway.  They're outstanding, cheap toroids.....

	Where exactly might I find this??  I realize you're in Australia,
but I'll bet even with shipping, they're a helluva lot cheaper than
"real spun toroids." 

	I guess they're completely sealed at purchase, then??  I'll bet my
upcoming coil would be awesome with three or four of those on top, and
would look cool, too.
