Yes - Brent Jesse over at audiotubes.com is extremely knowledgeable and is sitting on all kinds of tubes. I think a good amount of his stuff is higher end NOS, but I know he has some more budget range stuff, too.
He took the time to write me two very long e-mails answering all of my questions when I wanted to know about EL34's and 12AX7's for my Vox NT50, and he wrote an awesome piece
for my blog on NOS tubes. Very informative and worthwhile to read IMO.
Worst case, he can at least point you in the right direction. I barely know the guy but fully endorse him after the type of service I received from him. Rare these days.
