I want to buy some things for my (beginner) homegym for lifting. What I already have:
>2 dumbbells with some weights
>1 barbell with some weights
>half rack for dips and pullups

This is entertaining me now for couple of months. Now I'm thinking of buying this next:
>Ironmaster adjustable dumbbell (for quick adjusting)
>Good flat bench

That's around 1000€. Should I or are there better things to buy first?

From what I read is that the flat bench with dumbbells allow me to do most important exercises. Adjustable would be even better but not sure if I really need it. Are dumbbell bench presses alright or should I also invest into a proper rack for barbell bench presses? I'm a bit spooked out if something goes wrong with that as there is no one to help me.
