Cheap starter system for kids

A friend who is definitely not an audiophile has two kids who have gotten into vinyl using some junky all-in-one turntables that just now broke. He wanted my advice on helping them put together their new systems but definitely isn’t ready to jump into the deep end just yet.

I generally enjoy the game of building theoretical systems from scratch so hoped some of you would too. The system needs to be for beginners in their tweens/early teens, include a turntable, be relatively compact as it goes in a bedroom, does not need deep bass to avoid annoying their mom, and it needs to be as cheap as you can get with still good sound quality (he hasn’t given me a sure budget yet but definitely under $1k and the lower the better). He’s only comfortable with new/refurbished gear rather than used or vintage.

So far I’m leaning towards:
Turntable:
Project debut carbon - $400
or
Rega P1 - $475

Phono:
Schiit Mani - $130
or
Cambridge Alva Solo - $180 (if he’d rather pay $50 to avoid all the Schiit jokes from a tween boy)

Speakers: Audioengine HD3 - $350

Look forward to your ideas & comments.
