I buy mostly used tubes from sources that represent the product honestly. If the NOS tube you need is not in high demand there may not be much difference between used and new.
Unfortunately, most of our stereo gear uses the same dozen or so tubes, putting us in competition for dwindling NOS tubes.
Buy used that test good for most needs. If a tube is in a hyper critical situation such as the first stage of a phono, then selected NOS may be worth the premium price.
