The Tungsrams are excellent. I have 4 pairs and they are not for sale. I previously sold 2 additional pairs and now regret it.
I also have a pair of Valvos with pinched waists and D-getters that I will sell, but only for a small fortune.

Tubemonger.com has some if you want to deal with a domestic dealer. Otherwise, I see a few Euro sellers on eBay that look solid.
Buy extras. They aren't making them anymore. Says the OCD hoarder in me.
Best of luck.
