Digikey also offers those capacitors, but most are non-stock items with 
long delivery times and large minimum order quantities.

Digikey does give prices. Capacitors of that kind, suitable for legal 
limit lowpass filters, cost roughly $20 to $30 each. So for a set of six 
elliptic filters (30 capacitors) we would be looking at roughly $800 
plus shipping plus taxes, if we find a place that sells them in small 
quantities without charging extra. Shudder.

Long live homebrewing!
