As with anything, it depends what you want to do with it.
Casual plinking? Hunting? Tactical training?
I shot a Tactical rimfire rifle match yesterday and those with a 3x9 scope cussed it on the moving targets, since they had 2.5 seconds to put two rds each on five targets. All they saw was brown.
Red dots ruled the match, but a 1x4 scope would've, also.
Casual plinking, get whatever scope or optic you want and plenty of mags, including the new Ruger 25 rd mag.
Were it me, I'd get a Power Custom hammer and sear, ($60) a Tactical Innovations extended mag release (the one that curves under the triggerguard) ($35) and a Millet or Bushnell dot sight. ($60-$120) That'd be about $200
I won a .920 SS fluted barrel awhile ago, requiring a new stock. I got the Hogue Overmolded to go with it. This might add another $200 if buying new.
I like it quite a bit more now. It's much more versatile than before. But that's what I wanted.
