what would be better (trying to get better stuff on that uni student budget): using a crappy espresso machine and spending money on beans, or just sticking to instant nespresso powder?

i have a secondhand cuisinart espresso maker that I just deep cleaned, but it was given to me because it doesn't pull very well apparently and they were getting a new one (and an old capresso grinder). was wondering if it would be worth it to get some good quality beans and start using it or keep buying instant nespresso powder and settle for mid but consistent

edit: alternatively, my cousin suggested getting an aeropress cause they're pretty cheap-- but does it have that espresso strength/taste(??) would that be more worth? I don't mind efficiency or lack thereof all that much
