Personally I'd go Samwha HC from Cricklewood.Looking for a few of these if anyone has any left over from the group buy that happened a few years back.
The prices are good but the shipping is extortionate! Oddly, one of the caps they list doesn't appear to be one on the official Kendal site.The best supplier for the kendeil is Audiokit in italy.
Kendeil is Italian manufacturer
The price are very good
