I don't want to replace the broom
How come you don't want to replace the broom?
I don't want to buy something that's so expensive this time. I need money for other things.
If you do not have the money at this time, it is good to understand where your priorities lie. Rent would be more important than the broom.
I just don't have the money nor I want to spend it on a broom.
It is good you recognize the state your finances are in. It is important to be smart with your money and manage your purchases.
