Finding Hi-Fi abroad?

Is there a forum in Great Britain, Europe, and/or Asia for finding Hi-Fi gear produced in those areas, pieces of gear that didn't make it over to the States in large quantities? I am looking for a Townshend Audio Excalibur 3 Tone Arm, an item apparently thin on the ground here.

Happy Hunting.
Thanks guys. Hifishark I knew about, ukaudiomart is now added to my favorites list. The search continues!
