reccomendations? 73 dart sport or 75 RR?

Idk what your mechanical abilitys are but a demon clone from that is super easy and pretty cheap I'd say you could get the parts you need for around 500 if you shop around and most likely cheaper if you find a few in darts in fields or yards

id have to do some researching because 340s are hard to find around here and my mechanical abilities are 6/10 i would say
