From what i hear sat internet is only a solution in regions where still terrestrial broadband lines aren't available. If you have the possibility to get xdsl/cable/fibre optical/wireless internet access don't go for it.
The reasons are these:
Some contracts have limits on the amount of data you can dl or ul (if 2way). If you pass this limit you pay per GB and it can get very expensive. Lately there are unlimited services but let's say that you pay for a 512 dl connection and 2GB of data are guaranteed at this speed. If you exceed the 2GB the speed will fall since your data packets are of lower priority on the system compared to others who are still below the 2GB. I am not sure if this problem have all the sat-isp's but be warned. Have heard from a person that had 512 down and since he exceeded the limit the speed fell to analogue-modem-level !!!
There is also another problem:
Real satellite flatrates are expensive just because you need an uplink to satellite with a transmitter (costs at least 1500€) beeing installed on your dish and perfectly aligned and configured. If not then the whole network of the isp can break down. That's what someone told me knowing more. So the hardware is expensive and the monthly fees are too. This 2way provider

of what i have read in the DVBN-Forum seems to be quite ok although i haven't seen it with my own eyes and so i cannot really recommend it to anybody. But as good the service might be the ping times will be high since the signal has to travel a while to the sat, and beeing sent to the ground station to the isp. So don't be surprised if you see numbers like on an analogue connection. Knowing this you can forget online gaming over a 2way connection. I think also voice- and videochat won't work well or with very high delay.
Another one-way-provider is this one which is recommended of some people:

Finally i want to give you an idea also. If there are some people interested in your surrounding and a flatrate is available anyhow, either over sat or further away over dsl then over Wireless LAN an access could be provided to those beeing far away from the access point.
In Greece for example where flatrates are very expensive til the moment (120€ a month for a 384/128) people exchange data between them over WLAN. The network has risen in a few months to the biggest in Europe just because of the high dsl-fees. Although internet access isn't provided yet one can have theoretically up to 11Mbit/s transfer rates over the air. Practically it's about half of this speed. So if you live on the edge of a dsl- or cable-broadband area and have a friend or relative beeing inside he could do the connection and you over WLAN using his line and each of you pay half of the price. Just an idea which might help some here.
