Generate proxyv6

Hello.
Tried many proxyv6 generator tools but the quality is poor or limited.
My budget is not much so I need a more economical and effective tool.
It may be a bit difficult but if anyone knows please suggest me, all opinions are appreciated

I think you can consider IPFighter. I have created more than 100 v6 proxies on this tool. If your network allows, you can create unlimited v6 proxies.

wouldnt Vietnam be poor quality
