Any proxy website recommendation for buying 1x at once?

Hey.

I know quite a lot of proxy websites, but not many offer cheap shared/private proxies and allow you to buy only 1 at a time. They almost all start at 5 minimum. One I know on top of my head is proxy6.

Would anyone know of any others?

Thanks

have you actually asked any of the bhw proxy sellers
