Can you still buy Opella washing machine taps?

I used to use Opella washing machine taps, and I used them to plumb in my own washing machine and dishwasher. They were like the ubiquitous red and blue levered taps that break off, but with a plastic body. Instead of the flimsy plastic levers, they had a large plastic knurled wheel to turn it on and off. I found them much better, but the other type have the market sown up and I don’t like them. Can you still buy them?
