1. 25/2 DSL for $140/month (12 month contract with $40/mo seasonal disconnect)
2. 5G (60/0.03 which was 100/20 last summer until the nearby tower became overloaded).
3. LTE (see above) which I routinely get ~100/30 but which Verizon, at least, will not allow their boxes to use if it can connect via 5G, regardless of usability of the connection.
4. Fiber (100/100) at $89.95 (12m contract with $25/month seasonal disconnect). The fiber has higher speeds, but I didn't price them out. The costs were originally listed at $34.95 before they ran the lines, but they have upped them to $89.95 now that they are run to my lake home.
5. Starlink (supposedly 150/20 for Residential Lite which is available in my area) at $80/month on a month-to-month with purchase of a dish (I got mine refurbished for $135). I am routinely seeing ~400/40 with 25ms ping even though I shouldn't be. That said, the speeds are more variable (low as 120/7).

I would LOVE for there to be reasonably priced and very stable Internet for month-to-month, but there just isn't except for Starlink--at this point.
