Where do you guys buy tubes?

Question for Atmasphere:  Do you think JJ has resolved quality problems?  I had some KT88s from them a while back.  They sounded great but did not last.  Failed in a damaging way to the JoLida integrated I was running at the time.  I'd be pleased to hear they've resolved those issues, though I do note some of the suppliers above (Jim McShane & Kevin Deal) still do not carry any JJ product.  Just curious on your read of that situation.  Thanks.  

I typically buy vintage NOS tubes from Brent Jessee, service and quality are top notch.

Upscale Audio. I was satisfied with Kevin Deal's expertise and the care he took where tolerances were particularly tight with my equipment.

Tube Store in Canada. Very knowledgeable, well supplied and fast service. Great NOS selection.
