If your not a gamer, plan on using VOIP, or downloading huge amounts, satellite is your best option. You do have download limits, and you have very limited/restricted upload limits, and weather can be a factor, but it beats dial-up. You can buy equipment at good prices on fleabay and save quite a bit there.
If DSL or cable were an option, I woudn't give satellite a second thought, but when its that or dial-up, it would be satellite hands down. I had it where I used to live and work, and it was my ONLY option, couldn't even get dial-up, as we didn't even have phone lines...
