Is Dratini worth it

So I got fire red last week, and I’ve loved it. I’m about to attempt the celadon gym, and I’ve been playing the slots (I’m not addicted I swear)

I hav enough for Dratini, but I was curious if it was worth it at this point, considering the grind I’m gonna have to put in for Dragonite

ATM I have Pidgeotto, Hypno, Dugtrio, Pikachu (soon to be Raichu,) Nidoking and Wartortle

Is it worth it? Also how is my team atm? They’re all lvl 28-29 right now. This is the oldest Pokemon game I’ve ever played so it’s been a major difference from the newer ones I’m used to
