Kitchen cupboard door knobs

[LovingTheSunshine]

Hi
I updated our kitchen cupboard door knobs with some I bought from Laura Ashley. They were rubbish & wouldn't tighten very well. I have now thrown them away & want to buy some better quality ones but not spend a small fortune again. Other than the DIY stores, where is a good place to buy? Any online sites?
Thanks :)

Ikea?

Knobs and handles

Sometimes cupboard knobs won't tighten because the doors are too thin for the knobs.
You can put a couple of washers at the back of the doors between the screw and the door. This will take up the slack.
