[R-390] Crystal 200 KC

[wb5uom at hughes.net]

I got in on the tail en of this I guess. You might try (for grins):
http://www.icmfg.com/crystals.html#ranges

Now I know they are not really interested in selling just one or two BUT
I called a place one time looking for ONE special intergrated chip, not a
1000 or 10,000 just ONE. I called them and the lady said they didnt sell in
that small of quanity BUT if I was doing a pilot project they would send me
1- 20 for FREE !!
It took me just a microsecond to affirm this was a "pilot" project !!!
Have plenty of spares now!

So, it might not hurt to make a call!
