low cost base gnss

Hi everyone, has anyone made their own ntrip server with low cost receivers? I'm reading more and more articles about these receivers on "researchgate" etc., and it seems like a good option.

I am talking about receivers such as the following (Sorry for the advertising):

and the servers: RTK2Go or geoastra

thanks in advance
