Brandon at TubeWorld is extremely knowledgeable and stands behind his product with a money back guarantee.
So does Brent Jesse at http://www.audiotubes.com/.
As does Dennis Boyle at Chimera Labs who does not have as wide a stock but can often hook you up with great tubes at lower prices. Great guy to deal with.

With all three guys the knowledge and advice is top notch, product is great and packing and shipping are fast.
