I got something like this about 10 years ago and it's still going strong with basically daily wear. Sometimes leaves a bit of brown on my jeans but that washes off! I think I paid about £20, but inflation..

In my experience, the bit of a belt to fail is the buckle, so get one that is sewn in and not a clip. I've had too many clip belts fail and need to be fixed with tissue paper to be usuable. Really annoying.
