>>97503539shin ramyun is fairly spicy, look for the bone broth kind especially
sapporo ichiban is decent and fairly cheap
i like nissin raoh tonkotsu. sadly because of import restrictions it cant use the same formula as the overseas one with full on pork.
learn how to make ajitama and have a few on hand to juice up your ramen
scallions are cheap and everywhere so these toppings should be
look up how other people make their ramen, scope out what you can obtain reasonably to add to your rotation of toppings
