In my case 500/500 fiber @ ~$40-45/month, somewhere around $20-25/month for 100/50 4G and something like $60-65 for 1000/1000 fiber. Semi-rural areas are usually not far behind.

With neighborhood deals you can push those prices a bit.

Most (major) train lines have fiber buried next to them that is leased by the various telecoms which helped the expansion.

[Edit] Looked it up and a rural town in the southern parts where I used to live offers 1000/1000 from 5 different ISP's who are apparently fighting. They've all lowered prices recently, cheapest is at ~$30/month.
