Notebooks: Rhodia, Clairefontaine, Leuchtturm1917, or equivalent quality. Should be around $15 depending on size. Moleskines are no-go (ink bleeds through page)
Ink: Private Reserve is a nice starting point. I am particularly fond of their foam green. $11 for a 66ml bottle.
Shop: I really like Goulet Pens. Good service, amazingly careful packaging.
