the bamboo is outdated, get an intuos if you're looking for the Wacom quality but cant afford a cintiq, otherwise if those are still out of the price range everyone elses suggestions are good too
nibs are literally just plastic bitties so don't worry about buying those but I haven't had a good experience with parblo stuff, tablet practically fell apart within a couple of months. look into it if you want but don't skimp on quality
