Should I buy?

Price 600€ (almost 700$).

Animal stem
Animal sprocket
Subrosa om frame
Eclat forks
Shadow 10" bars
Shadow simone tires
Eclat wheels
Fit cranks

I already have way to many parts.
Frame would fit my size and the only parts I really want are the animal stem and sprocket.

I could spend around ~500€ for a new animal stem and new frame, but the sprocket is not available anywhere…

Idk if I should pull the trigger..
