Right now, it's either dial-up, satellite, or wireless broadband for us.
Well actually I don't live in the states, but I actually do networking for Swisscom, and therefore my advise is, go with dial-up. Since you already said yourself wireless is "meh", satellite is meher if not the mehest of the choices. It's somehow same technology as wireless bb, there simply is no cable, but the distance is massively bigger (going all the way into space and back again).
I don't know your expectations and needs in terms of speed, but over here we get 20MB/s downstream on a 4-wire-cable and 50MB/s on a coax-cable (which won't be possible as dial solution I suppose). Upload has to be seen.
Bottom line, if you ask me I'd definitely go with dial-up, it's the most stable option in my eyes, if you don't have the wireless-access-point right aside your house - even then, personally I'd sill go with the cable.
Since there was no word about prices
and if you already talk to the provider to expand their lines with all the construction-works, isn't there any way you might get fibre instead of copper?
