Jameco has them for about $2.50 each here:


Be careful to order "83-1SP," and not 83-1SP-1050, which is the "Astroplate"
version that isn't very easy to solder...

Hi Steve and thanks for the reply. Do you know who has the best price on 
the Amphenol 83-1SP's? I'll order some right away!

Thanks again,
